4. For a binomial distribution with a trial repeated 4 times (n = 4) and probability of success on a single trial p = 0.75 find the probability of: a) no successful outcomes (3 points) P(X=0) = A) 0.0039 B) 0.0080 C) 0.0469 D) 0.9961 b) more than 1 successes (5 points) P(X> 1) = A) 0.0508 B) 0.9492 C) 0.8640 D) 0.8912 In each case show the result of calculations and circle one of the multiple choice answers.

Assume that a procedure yields a binomial distribution with a trial repeated n times. Use the binomial probability formula to find the probability of x successes given the probability p of success on a single trial. n=5, x = 3, p = 0.55 P(3) = (Round to three decimal places as needed.)
