# In Exercises 25–40, use the given information to find the indicated probability. [HinT: See Quick Examples 14–16.] P ( A ∪ B ) = .9 , P ( B ) = .6 , P ( A ∩ B ) = .1 . Find P ( A ) .

To determine

To calculate: The value of P(A) where probability of A is P(AB)=0.9, probability of B is P(B)=0.6 and the probability of AB is P(AB)=0.1.

Explanation

Given Information:

The probability of A is P(AB)=0.9, probability of B is P(B)=0.6 and the probability of AB is P(AB)=0.1.

Formula used:

If A and B are any two events,

P(AB)=P(A)+P(B)P(AB)

Calculation:

Consider the provided values of probabilities,

P(B)=0.6,P(AB)=0.1 and P(AB)=0
