NCERT Class X Chapter 14: Probability Exercise 14.1 Question 5

Question:

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

Given:

P(E) = 0.05

To Find:

P(not E)

Formula:

P(not E) = P(E') = 1 - P(E)

Solution:

We are given that P(E) = 0.05.

The probability of the complement of an event E, denoted as P(not E) or P(E'), is given by the formula:

P(not E) = P(E') = 1 - P(E)

Substituting the given value, we get:

P(not E) = P(E') = 1 - 0.05

P(not E) = P(E') = 0.95

Resul:

Therefore, the probability of 'not E' represented by P(E') is 0.95
