Problem 1E

Let A and B be events with P(A) = 0.8 and P(A ∩B) = 0.2. For what value of P(B) will A and B be independent?

Step-by-Step Solution:

Solution :

Step 1 of 1:

Let A and B be the two events.

The probability of A is

P(A)=0.8 and

=0.2

Our goal is :

We need to find the probability the value of P(B).

Now we have to find the value of P(B).

Here A and B be the two independent events.

The formula of the .

Therefore the value of P(B) is 0.25.
