Answer:
[tex]P(B) = 0.64[/tex]
Explanation:
Given
[tex]P(A) = 0.61[/tex]
[tex]P(A\ n\ B) = 0.39[/tex]
Required
Determine P(B)
If A and B are independent, then:
[tex]P(A\ n\ B) = P(A) * P(B)[/tex]
Substitute values for P(A) and P(A n B)
[tex]0.39 = 0.61 * P(B)[/tex]
Make P(B) the subject
[tex]P(B) = \frac{0.39}{0.61}[/tex]
[tex]P(B) = 0.64[/tex] --- approximated
