Thirty percent of all customers who enter a store will make a purchase. Suppose 10 customers enter the store, and that they make independent purchasing decisions.
(a) Let X be the number, out of the 10 customers in the store, who will make a purchase. Write the binomial probability density function for this situation.
(b) Use the binomial distribution to calculate the probability exactly 5 customers make a purchase.
(c) Find the probability that 4 or fewer customers make a purchase.
(d) Find the probability that 7 or more customers make a purchase.

Question 1) Some customers have not purchased any products. The store hopes to encourage these customers to buy their products through various discount coupons. For this purpose, the store's management would like to see all details of customers who have never purchased any products. Use at least one RIGHT JOIN in this query.
Question 2) Some products have never been purchased by any customer. The store's management is considering removing these products from their shelves. They would like to get a list containing the name of vendors and the names of their products that have never been bought by any customer. Use at least one LEFT JOIN in this query.
