Question

Suppose A and B are independent events. If P(A)= 0.4 and P(B) = 0.85, what is P(A and B)?

Answer 1

The value of the P(A∩B) is equal to 0.04.

We have given that,

P(A)= 0.4 and P(B) = 0.85.

We have to determine the  P(A and B)

What is the formula for Independent Events?

For Independent Events,

P(A) × P(B) = P(A∩B)

so we have, P(A∩B) = 0.4×0.1

P(A∩B) = 0.04

P(A') = 1 - 0.4 = 0.6

This information can be represented on a Venn diagram as shown below

P(A'∪B) means the union of everything that is not A with everything that is B

P(A'∪B) = 0.06 + 0.54 + 0.04

P(A'∪B) = 0.64
