Question

The owner of a small deli is trying to decide whether to discontinue selling magazines. He suspects that only 10.7% of his customers buy a magazine and he thinks that he might be able to use the display space to sell something more profitable. Before making a final decision, he decides that for one day he will keep track of the number of customers that buy a magazine. Assuming his suspicion that 10.7% of his customers buy a magazine is correct, what is the probability that exactly 5 out of the first 13 customers buy a magazine? 0.00266771 0.00128824 0.00729977 0.00194043 0.00448111 0.00757907

Step 1

This is a binomial probability problem. The formula for binomial probability is: $$P(X=k) = C(n, k) * p^k * (1-p)^{(n-k)}$$ Where: - $$P(X=k)$$ is the probability of exactly $$k$$ successes in $$n$$ trials. - $$C(n, k)$$ is the binomial coefficient, calculated as Show more…
