Let’s say your initial timeshare purchase is that average price of $22,000 with the yearly maintenance fee of $980. Over the next 10 years of using your timeshare, you would be eligible to stay 60 nights (each week’s stay is seven days and six nights). Check out these numbers: As before, you determine the total outcome possibilities by multiplying the number of sides on one die by the number of sides on the other. Unfortunately, counting the number of outcomes you’re interested in means a little bit more work. For getting a total score of 4 on two dice, this can be achieved by rolling a 1 and 3, 2 and 2, or a 3 and 1. A prime number is a whole number greater than 1 whose only factors are 1 and itself. A factor is a whole number that can be divided evenly into another number. The first few prime numbers are 2, 3, 5, 7, 11, 13, 17, 19, 23 and 29. Numbers that have more than two factors are called composite numbers. The number 1 is neither prime nor composite.

It has only been pulled out of the barrel 204 times, while the most common number 23 has come up 266 times. If we roll a standard 6-sided die, describe the sample space and some simple events. The sample space is the set of all possible simple events: {1,2,3,4,5,6} Some examples of simple events: We roll a 1 We roll a 5 Some compound events: We roll a number bigger than 4 We roll an even number

(a) Rolling a number less than 5 on a die. (b) Tossing heads on a fair coin. (c) Drawing an ace from an ordinary 52-card deck. Solution. (a) The probability of rolling a number less than 5 is 4 6 and that of rolling 5 or 6 is 2 6. Thus, the odds in favor of rolling a number less than 5 is 4 6 ÷ 2 6 = 2 1 or 2:1 (b) Since P(H) = 1 2 and P(T) = 1 2as the number of flips in one toss increases, the ratio of time spent in each state would oscillate between greater-than-1:1 and 1:1, and approach a limit of 1:1 to 1:1. Starting on H and assuming a constant spin rate & time on one side = t, the ratio of time on each side would be Ht, Ht:Tt, H2t:Tt, H2t:T2t, H3t:T*2t,...

2) A card is randomly selected from a deck of 52 cards. What is the probability that the card is a “10” or a “face card”? 3) You roll a fair die. What is the probability that you roll a “1” or an even number? 4) In Ms. Carr’s Math class, 9 of the 14 girls said they “like math”, and 7 of the 16 boys said they “like math”.Aug 03, 2020 · In this case, X could be 3 (1 + 1+ 1), 18 (6 + 6 + 6), or somewhere between 3 and 18, since the highest number of a die is 6 and the lowest number is 1. A random variable is different from an ...

If a fair 6-sided die is rolled 100 times, what percentage of the time do we expect x to be between 20 and 40? This is a binomial process, with "success" being defined as getting a 2 or 3. So p = .3333, n =1002. A fair coin is tossed three times; let X denote the number of heads on the rst two tosses, Y the number of heads on the last two tosses. a) Are X and Y independent? Prove it. No; for example, P[X = 0] = P[Y = 0] = 1 4, while P[X = 0;Y = 0] = 1 8 6= (1 4)2. b) Give the distribution of Z = X Y. The four possible values of Z have probabilities ... If you flip one fair coin and follow it with the toss of one fair, six-sided die, the answer to c is the number of outcomes (size of the sample space). What are the outcomes? (Hint: Two of the outcomes are H1 and T6.) Event A = heads (H) on the coin followed by an even number (2, 4, 6) on the die. A = {_____}. Find P(A). What is the standard deviation of the even number (2, 4, or 6) outcomes? A. 18 B. 9 C. 5 D. 3 E. 1. The manager of the local grocery store has determined that, on the average, 4 customers use the service desk every half-hour.

English descriptive writingApr 30, 2009 · I’m not sure why you would need a D5 for any reason whatsoever. You can get a number from 1 to 5 generated through its unique, completely untrustworthy shape. I don’t care if laboratory tests show this thing gives you a fair roll each time, it is the fact that it doesn’t look like it’s going to give you a fair roll is the problem.

This is called the expectation or expected value of the payoﬀ. It is also called the fair price of ... Dec 04, 2017 · In the board game Monopoly, we move our token based on the sum of the dice rolls, and if we’ve rolled doubles, we can roll again. Looking at the example outcomes above, it’s obvious that the outcomes cannot be equally likely if we care about the sum of the dice rolls. The outcomes (1, 5), (2, 4) and (4, 2) all have sum 6.

Jan 15, 2020 · Before thinking about all the possible outcomes and probabilities involved, make sure to understand the problem. For example, consider a die-rolling game that costs $10 per play. A 6-sided die is rolled once, and your cash winnings depend on the number rolled. Rolling a 6 wins you $30. Rolling a 5 wins you $20.

faces comes up, we can just roll the die again. If n= 2, a coin could be used to perform the experiment. We will be particularly interested in repeating a chance experiment a large num-ber of times. Although the cylindrical die would be a convenient way to carry out a few repetitions, it would be di–cult to carry out a large number of ...Suppose you are playing a game where you can roll a single die one or two times. Your objective is to get a high number. After the first roll you can choose whether to keep the number you got or re-roll. Then the best strategy is to keep a 4, 5, or 6, while re-rolling a 1, 2, or 3 (try to convince yourself of this). Baby calves for saleconsider an experiment in which we roll a standard six-sided die, the sample space is W = f1,2,3,4,5,6g. Collections of outcomes in the sample space W are called events, and we often use capital Roman letters to denote these collections. We might be interested in the event that we roll an even number, for example. If we call this event E, then ... (iv) Favourable outcomes i.e. to get an even number are 2, 4, 6, 8, 10, and 12. So, total number of favourable outcomes i.e. to get an even number is 6. We know that, Probability = Number of favourable outcomes/ Total number of outcomes. Thus, the probability of getting an even number = 6/12 = 1/2. 22. In a class, there are 18 girls and 16 boys. Next we count the frequency or number of times a specific value of X occurs. Because each of the eight outcomes is equally likely to occur, we can calculate the probability of the random variable X by dividing the frequency of each value by the total number of outcomes. We summarize our results as follows: p p p p p p p p [0, 2p)
