Explanation / Answer

7) Solution :

A probability is a value between 0 and 1 inclusive. Probability 0 mean the event is impossible, probability of 1

means the event is certain.

Here a, b and e are between 0 and 1, that are the probabilities.

Since c and d are not between 0 and 1, they cannot be probabilities.
