Assume a sequence of independent trials, each with probability p of success. Use the Law of Large Numbers to show that the proportion of successes approaches p as the number of trials becomes large. It may be useful to think of this problem as a Bernoulli distribution and to then calculate the mean.

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...

(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).

A Bernoulli Trials experiment has p=15/23 probability of success on each trial. What is the expected number of successes in five trials? What is the expected number of successes in 16 trials? What is the expected number of failures in 69 trials? Enter your answers as whole numbers or FRACTIONS in lowest terms.

Suppose that total 5 independent trials having a common probability of success 1/3 are performed. If X is the number of successes in the first2 trials, and Y is the number of successes in the final 3 trials, then X and Y are independent, since knowing the number of successes in the first 2 trials does not affect the distribution of the number of successes in the final 3 trials (by the assumption of independent trials).
