Question

A local bakary has determined a probability distribution for the number of cheesecakes that they sell in a given day. X= #sold: 0 5, 10 15, 20. Probability: 0.22, 0.21, 0.2 ...? 0.07 . What is the probability of selling 15 cheesecakes in a given day? What is the probability of selling at least 10 cheesecakes? What is the probability of selling 5 or 15 chassescakes? What is the probability of selling 25 cheesecakes? Give the expected number of cheesecakes sold in a day using the discrete probability distribution? What is the probability of selling at most 10 cheesecakes?
