If a binomial distribution applies with a sample size of n = 20, find the values below. a. The probability of 5 successes if the probability of a success is 0.20 b. The probability of at least 7 successes if the probability of a success is 0.40 c. The expected value, n = 20, p = 0.25 d. The standard deviation, n= 20, p = 0.25 a. The probability of 5 successes if the probability of a success is 0.20 is (Round to four decimal places as needed.) b. The probability of at least 7 successes if the probability of a success is 0.40 is (Round to four decimal places as needed.) c. The expected value is (Type an integer or a decimal.) (Round to four decimal places as d. The standard deviation is needed.)
