Explanation / Answer

Please post 1 question per post, as per forum rules. We aren't supposed to answer assignment questions, so you may break them down.

Here' answer to the question 2.

2. Complement method of finding out probability means we find the answers by subtracting from 1 the opposite probability

For example , P(A) + P(A') = 1, where A is some event

So, P(A') = 1-P(A)

Hence, e is correct
