Question

The probability of an occurrence of event A is 0.7 and that of the occurrence of event B is 0.3 and the probability of occurrence of both is 0.4

Options

• True

• False

Answer 1

This statement is False.

Explanation:

Here, P(A) = 0.7, P(B) = 0.3

∴ P(A ∩ B) = P(A) × P(B)

= 0.7 × 0.3

= 0.21

But the given probability is 0.4
