Tugas A

Speedy Saverio’s Pizza House claims to cook and deliver 90% of pizzas within 15 minutes of

busy Saturday night, Saverio has to make 150 deliveries.
a. How many deliveries are expected to be made within 15 minutes of placing the order?
b. What is the probability of receiving a free pizza on this night?
c. If Saverio loses an average of $4 for every late delivery, how much would he expect to
lose on late deliveries this night?
