the manager of a grocery store reports that there is a 12 percent chance that a customer buys apples during a shopping trip, a 5 percent chance that a customer buys apples and carrots, and a 17 percent chance that a customer buys apples or carrots. what is the probability of a customer buying carrots? 1.4 percent 5.0 percent 10.0 percent 11.4 percent

Answer

Explanation:

Step1: Use the addition - rule formula

Let (P(A)) be the probability of buying apples, (P(C)) be the probability of buying carrots, and (P(A\cap C)) be the probability of buying both. The formula for (P(A\cup C)=P(A)+P(C)-P(A\cap C)). We know (P(A) = 0.12), (P(A\cap C)=0.05), and (P(A\cup C)=0.17).

Step2: Rearrange the formula to solve for (P(C))

[P(C)=P(A\cup C)+P(A\cap C)-P(A)] Substitute the given values: (P(C)=0.17 + 0.05-0.12).

Step3: Calculate the value of (P(C))

[P(C)=0.1]

Answer:

10.0 percent
