# Let A and B be events with P(A) = 0.5 and P(A n Bc) = 0.4.

Statistics for Engineers and Scientists | 4th Edition

Problem 2E

Let A and B be events with $$P(A)=0.5$$ and $$P\left(A \cap B^{c}\right)=0.4$$. For what value of $$P(B)$$ will A and B be independent?

Equation Transcription:

Text Transcription:

P(A)=0.5

P(ABc)=0.4

P(B)

Accepted Solution
Step-by-Step Solution:

Solution :

Step 1 of 1:

Let A and B be the two events.

The probability of A is

P(A)=0.5 and

=0.4

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 .

Then,

We know that P(A)=0.5 and =0.4.

Now,

Therefore the value of P(B) is 0.2.
