# Which of the following cannot be the probability of an event?

(A) 2/3 (B) –1.5 (C) 15% (D) 0.7

**Solution:**

We use the basic concepts of probability in order to answer the question given.

We know that the probability of an event E is in between 0 and 1, that is, 0 ≤ P(E) ≤ 1 and it cannot be less than 0 and greater than 1. So, (B) - 1.5 cannot be the probability of an event because it cannot be negative.
