To find the probability that at least 1520 of the people in the sample find shopping frustrating, we must add the binomial probabilities of all outcomes from X = 1520 to X = 2500. This isn’t practical. a. We can use our calculator to find the probability that X is less than or equal to 1519 and subtract from 1. What answer does this give? b.
