Long and McQuade is a chain of stores that rents musical instruments. Suppose for the sake of this question that there are only two types of instruments that a customer will rent: violins and guitars. Suppose a store in the chain stocks 25 violins and 50 guitars, and that sizing is not an issue, and that rentals are returned after 1 day. Suppose 60% of customers will rent violins and 40% will rent guitars. Suppose 10 customers enter the store on Tuesday. What is the probability that exactly 6 customers want to rent a guitar? Round your answer to 4 decimal places.
