Consider a random experiment of throwing three perfectly balanced and identical coins. Suppose that for each toss that comes up heads we win $3, but for each toss that comes up tails we lose $4. Clearly, a quantity of interest in this situation is our total wining. Let X denote this quantity. (n) What are the vilues that the random variable X takes? (b) Find P(X = 9). (e) Find P(X =-5).

Consider the following game. A fair coin is flipped until the first tail appears; we win $2 if it appears on the first toss, $4 if it appears on the second toss, and in general if it first occurs on the k-th toss. Let the random variable X denote our winning. How much should we have to pay in order for this to be a fair game? Note: A fair game is one where the difference between the ante and E(X) is 0
These questions concerns the following situation. There is a rain on a football ground. The ground is 100 meters long and 70 meters wide. Model the event of a raindrop falling as a randomly selected point in the rectangle pictured.Lets imagine the following random variables: X is the x-coordinate where a raindrop falls, Y is the y-coordinate of where a raindrop falls, and Z=X+Y. CHOOSE ONE AND SHOW THE PROCESS. Which one of the following statements are true? * a) X and Y are independent b) X and Z are independent c) Y and Z are independent
An ordinary (fair) coin is tossed 3 times. Outcomes are thus triples of "heads" (h) and "tails" (t) which we write hth, ttt, etc. For each outcome, let N be the random variable counting the number of heads in each outcome. For example, if the outcome is thh, then N (thh)=2. Suppose that the random variable X is defined in terms of N as follows: X=2N²-6N-4. The values of X are given in the table below. ttt hhh hth hht tht htt thh tth Value of X -4 -4 -8-8-8-8-8-8 Outcome Calculate the probabilities P (X=x) of the probability distribution of X. First, fill in the first row with the values of X. Then fill in the appropriate probabilities in the second row. Value x of X P(X=x) 7 00 X S

Two coins are taken at random (without replacement) from a bag containing 6 nickels, 5 dimes, and 4 quarters. Let X denote the random variable given by the total value of the two coins. Find E(X). (Round your answer to four decimal places.)

Suppose that X, Y, and Z are jointly distributed random variables, that is, they are defined on the same sample space. Suppose that we also have the following.

A fair dice is thrown once. The random variable Y is related to the number B thrown on the dice as follows. If B is even, then Y is half B, otherwise Y is triple B. Find the mode and E(Y). Select one: no mode and E(Y) = - mode = 3 and E(Y) = 4 mode = 2 and E(Y) = mode = 3 and E(Y) = mode = 5 and E(Y) =

Let the random variable X represent the number of jars in a sample of size n with broken seals. If six jars are r=4n=6 selected at random: N=14 r =
