MAT 150 Statistics Assignment #11 Binomial Probability Given the number of trials and the probability of success, determine the probability indicated: a. n-15, p. 0.4, find P(4 successes) b. n-12.p-0.2, find P(2 failures) c. n-20,p-0.05, find P(at least 3 successes) 1. An FBI survey shows that about 30% (i.e. 0.3) of all property crimes go solved. Suppose that in New York City 15 such crimes are committed and they are each deemed independent of each other 2. What is the...
Problem 1 Consider a sequence of n+m independent Bernoulli trials with probability of success p in each trial. Let N be the number of successes in the first n trials and let M be the number of successes in the remaining m trials. (a) Find the joint PMF of N and M, and the marginal PMFs of N and AM (b) Find the PMF for the total number of successes in the n +m trials. Problem 1 Consider a sequence...

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...
