2. A box contains tickets marked 1,2,3, n. A ticket is drawn at random from the box. Then this ticket is replaced in the box and a second ticket is drawn at random. Find the probability the second number drawn is smaller than the first. (Recall 1 + 2 + 3 + + k-en! i k(k+1) ).

Two tickets are drawn from a box with 5 tickets numbered as follows: 1,1,3,3,5. If the tickets are drawn with replacement, find the probability that the first ticket is a 1 and the second ticket is a 5. If the tickets are drawn without replacement, find the probability that the first ticket is a 1 and the second ticket is a 3. If the tickets are drawn without replacement, find the probability that the first ticket is a 1 and...

1. In a box there are three numbered tickets. The numbers are 0, 1 and 2. You have to select (blindfolded) two tickets one after the other, without replacement. Define the random variable X as the number on the first ticket and the random variable Y as the sum of the numbers on your selected two tickets. E.g. if you selected first the 2 and second time the 1 , then X = 2 and Y-1 +2 = 3. a./...

One thousand raffle tickets are sold at $1 each. Three tickets will be drawn at random (without replacement), and each will pay $191. Suppose you buy 5 gats. (A) Create a payoff table for 0, 1, 2, and 3 winning tickets among the 5 tickets you purchased. (If you do not have any winning tickets, you lose $5. If you have 1 winning...

One thousand raffle tickets are sold at $1 each. Three tickets will be drawn at random (without replacement), and each will pay $198. Suppose you buy 5 tickets. (A) Create a payoff table for 0, 1, 2, and 3 winning tickets among the 5 tickets you purchased. (If you do not have any winning tickets, you lose $5, if you have 1 winning ticket, you net $193 since your initial $5 will not be returned to you, and so on.)...

Consider a box which contains some tickets. Suppose a fraction, p, of the tickets have a "1" written on them; the remaining have a "0". a. Let X denote the number on a ticket which is randomly drawn from the box. Fill in the first blank in the following sentence with the expected value of X and the second blank with the standard deviation of X. We expect X to be P give or take sqrt(p(1-p)) Write a few sentences...

question D good descriptive answer please.
3. Sampling with and without replacement. Sarnpling urith replacement: A box contains tickets marked 1,2,...,u. A ticket is drawn at random from the box. Then this ticket is replaced in the box and a second ticket is drawn at random. Find the probabilities of the following events a) the first ticket drawn is number I and the second ticket is number 2 b) the numbers on the two tickets are consecutive integers, meaning the...

9. A ball is drawn from a box containing three balls, one red, one blue, and one green. The ball is returned and a second ball is drawn. A tree diagram is drawn to give the outcomes of the experiment with respect to the colors of the two balls. If x represent the number of red balls in the two selected. Must show tree diagram, sample space, and your work. 20 pts. a. What are the possible values of x?...
