Q 12 / Statistics and Probability

Assuming the binomial distribution applies with a sample size of n = 20, find the values below. a. the probability of 5 or more successes if the probability of a success is 0.50 b. the probability of fewer than 4 successes if the probability of a success is 0.20 c. the expected value of the random variable if the probability of success is 0.55 d. the standard deviation of the random variable if the probability of success is 0.55 a. If the probability of a success is 0.50, the probability of 5 or more successes is. (Round to four decimal places as needed. b. If the probability of a success is 0.20, the probability of fewer than 4 successes is (Round to four decimal places as needed.) c. If the probability of success is 0.55, the expected value of the random variable is (Type an integer or a decimal.) d. If the probability of success is 0.55, the standard deviation of the random variable is (Round to four decimal places as needed.)
