Answer 2

Answer:

(b) 1 is the answer.

Since complementary events are mutually exclusive, we can use the special addition rule to find its probability. Furthermore, complementary events are all inclusive, so they make the sample space when combined, so their probabilities have a sum of 1. The sum of the probabilities of complementary events is 1.
