Problem 5 (10 points). Suppose that the independent Bernoulli trials each with success probability p, are performed independently until the first success occurs, Let Y be the number of trials that are failure. (1) Find the possible values of Y and the probability mass function of Y. (2) Use the relationship between Y and the random variable with a geometric distribution with parameter p to find E(Y) and Var(Y).

The geometric distribution is a probability distribution of the number X of Bernoulli trials needed to get one success. For example, how many attempts does a basketball player need to get a goal. Given the probability of success in a single trial is p, the probability that the xth trial is the first success is: Pr(x = x|p) = (1 - p*-'p for x=1,2,3,.... Suppose, you observe n basketball players trying to score and record the number of attempts required...

(5) Suppose we conduct five independent Bernoulli trials, each with a 60% probability of success. (a) Find the probability of each: • 0 successes • 1 success • 2 successes • 3 successes • 4 successes • 5 successes (b) Plot the probability mass function (pmf) and the cumulative probability distribution (cdf) for the number of successes in the five trials (using your findings from part a).

The binominal assumes that the trials are independent. Group of answer choices True False In an attempt to minimize no-shows on high-demand days a golf course has implemented an online check-in procedure. Preliminary results indicate that once a golfer has checked in, there is only at 20% chance that he or she will be a no-show. This chance of being a no-show can be modeled using the binomial distribution. If 15 golfers have checked in using this process, what is...
