(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).

You perform a sequence of m+n independent Bernoulli trials with success probability p between (0, 1). Let X denote the number of successes in the first m trials and Y be the number of successes in the last n trials. Find f(x|z) = P(X = x|X + Y = z). Show that this function of x, which will not depend on p, is a pmf in x with integer values in [max(0, z - n), min(z,m)]. Hint: the intersection of...
