# If P(E) = 0.05, what is the probability of ‘not E’?

**Solution:**

We will use the basic concepts and formulae of probability to solve the problem.

Probability of (E) = 0.05

We know that,

Probability of (E) + Probability of (not E) = 1

0.05 + Probability of (not E) = 1

Probability of (not E) = 1 - 0.05

Probability of (not E) = 0.95

Therefore, the probability of 'not E' is equal to 0.95.
