Suppose that independent Bernoulli trials, each having probability p = 0.4, of being a success are performed until a total of r = 3 success is achieved. Let X be the number of trials required. a) What are the possible values for X? b) If X = n, find P (X = n). c) What is the probability of having 3 success before having 5 failures?
