Part 2: The owner of a pet store is trying to decide whether to discontinue selling specialty clothes for pets. She suspects that only 4% of the customers buy specialty clothes for their pets and thinks that she might be able to replace the clothes with more interesting and profitable items on the shelves. Before making a final decision she decides to keep track of the total number of customers for a day, and whether they purchase specialty clothes for their pet. Assuming the pet store owner is correct in thinking that only 4% of her customers purchase specialty clothes for their pets, how many customers should she expect before someone buys a garment for their pet? l. 2. What is the probability that she does not sell a gament until the 7th customer? Show work. What is the probability that exactly 3 of the first 10 customers buy specialty clothes for their pet? Show work. 4. What is the probability that at least 3 of the first 40 customers buy specialty clothes for their pet? Show work.
