The binomial random variable x consists of n = 60 trials and has the probability of success of 0.4. Using the normal approximation, compute the probability that there are at least 20 successes.
Added by Michael O.
Step 1
The mean of a binomial distribution is given by the formula: mean = n * p, where n is the number of trials and p is the probability of success. In this case, n = 60 and p = 0.4, so the mean is: mean = 60 * 0.4 = 24. The standard deviation of a binomial Show more…
