(b) exactly 1 of these items?
ANSWER:
Step 1 of 3
A customer who visits the suit department of a certain store will purchase a suit with probability 0.22, a shirt with probability 0.30, and a tie with probability 0.28.
The customer will purchase both a suit and a shirt with probability 0.11, both a suit and tie with probability 0.14, and both a shirt and a tie with probability 0.10.
And a customer will purchase all 3 items with probability 0.06.
(a) We have to find the probability that a customer purchases none of these items.
(b) We need to find the probability that a customer purchases exactly 1 of these items.
