The situation described in Exercise 27 featured the weekly deliveries of two suppliers. Deliveries from supplier A are late 7% of the time. Deliveries from supplier B are late 3% of the time. Two percent of the time both deliveries are late. Use a Venn diagram to answer the following questions:

a. What’s the probability that at least one of the deliveries is late?

b. What’s the probability that neither of the deliveries is late?

c. If supplier A’s delivery is late, how likely is it that supplier B’s delivery is late as well?

d. What’s the probability that supplier A’s delivery is late but supplier B’s delivery is not?
