    Answer:

    P(A)=\frac{P(B\cap \: A)}{P(B|A)}

    Step-by-step explanation:

    Since event B is dependent on event A,

    P(B\cap\: A)\ne P(B) \times P(A)

    We also have the condition that, event A occurs before event B.

    So probability of B given A is

    P(B|A)=\frac{P(B\cap \: A)}{P(A)}

    We now solve for P(A) to get:

    P(A)=\frac{P(B\cap \: A)}{P(B|A)}
