Question 1145407: Two industrial cleaning products salesman A and B, must each make two calls per day, one in the morning and one in the afternoon. Salesman A has a probability of 0.45 of selling a cleaner on any call, while salesman B (a novice) has a probability of 0.2 of a sale. The two salesman work independently of each other, and each salesman’s morning and afternoon results are independent of each other.

1.2) Find the probability that salesman A makes no sales (rounded off to three decimals)? [1.5]
1.3) Find the probability that salesman B makes one sale for the day (rounded off to two decimals)? [2]
1.4) Find the probability that salesman B makes no sales (rounded off to two decimals)? [1.5]
1.5) Find the probability that either salesman A makes one sale or salesman B makes one sale (rounded off to three decimals)? [3]
