You own an ice-cream shop. Every day when you open the shop, there is an Exp( 1 10 ) random waiting time, in minutes, before the first customer arrives. 1. When the waiting time for the first customer exceeds 20 minutes, it is a bad day. Approximate the probability that you will have between 50 and 60 bad days in a year (365 days). Justify your use of this approximation approach. 2. When the waiting time for the first customer is shorter than 3 seconds (i. e., 0.05 minutes), it is a great day. Approximate the probability that you will have exactly 3 great days in a year (365 days). Justify your use of this approximation approach.
