Question 1206244
.
Suppose that P(A) = 0.3 and P(A ∩ B) = 0.06.
Find P(B|A).
~~~~~~~~~~~~~~~~~~


<pre>
P(B|A) is the conditional probability that event B will happen given that event A happens.

                              P(A ∩ B)
By the definition,  P(B|A) = ----------.
                                P(A)


Substitute the numbers and get  P(B|A) = {{{0.06/0.3}}} = {{{1/5}}} = 0.2.    <U>ANSWER</U>
