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 1 of 1:
Let A and B be the two events.
The probability of A is
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.
