Hi, I was looking at the answers for the below problem. I will like to know how 0.8666 was obtained in part A and 0.2650 in part B. An excel or clear hand written formula will be appreciated. Here is the problem: A restaurant chef prepares a tossed salad containing, on average, 5 vegetables per day. Find the probability that the salad contains more than 7 vegetables on i) a given day and on ii)3 of the next 6 days?
