Answer:
![P(B) = 0.64](https://tex.z-dn.net/?f=P%28B%29%20%3D%200.64)
Explanation:
Given
![P(A) = 0.61](https://tex.z-dn.net/?f=P%28A%29%20%3D%200.61)
![P(A\ n\ B) = 0.39](https://tex.z-dn.net/?f=P%28A%5C%20n%5C%20B%29%20%3D%200.39)
Required
Determine P(B)
If A and B are independent, then:
![P(A\ n\ B) = P(A) * P(B)](https://tex.z-dn.net/?f=P%28A%5C%20n%5C%20B%29%20%3D%20P%28A%29%20%2A%20P%28B%29)
Substitute values for P(A) and P(A n B)
![0.39 = 0.61 * P(B)](https://tex.z-dn.net/?f=0.39%20%3D%200.61%20%2A%20P%28B%29)
Make P(B) the subject
![P(B) = \frac{0.39}{0.61}](https://tex.z-dn.net/?f=P%28B%29%20%3D%20%5Cfrac%7B0.39%7D%7B0.61%7D)
