Answer:
0.06 or 6% probability
Explanation:
At a gas station, 84% of customers buy gasoline
P (A) =
= 0.84
5% of customers buy gasoline and a beverage
P (B) =
= 0.05
Equation of conditional probability = P (A and B) = P(A) × P(B/A)
= P(B/A) = P (A and B) / P(A)
= P ( B/A ) =

= 0.0595 ≈ 0.060 or 6%
The probability that a customer who buys gasoline also buys a beverage is 0.060 or 6%.
