Check the hint for the answer

On the AP Exam (and my test), you are provided with the following two equations:

General Addition Rule

null

Remember, if two events A and B are Mutually Exclusive, both events CANNOT happen at the same time. You can check this by verifying that P(A and B) = 0.

Applying that to the formula above, it means that you can calculate the probability of A or B by simply adding the probabilities together, assuming they are Mutually Exclusive.

P(A or B) = P(A) + P(B), if A & B are mutually exclusive

The other equation you are given:

Conditional Probability equation

null

This equation can be used to calculate P(A|B). Alternatively, it can be rearranged to calculate

P(A and B), shown below

P(A n B) = P(B)*P(A|B)

Remember, if events A and B are Independent, then knowing whether or not event A happen has NO impact on whether B happens.

P(A|B)=P(A|B^C)=P(A)

This also means the equation above becomes:

P(A and B) = P(B) * P(A), for independent events.

Use the Conditional Probability Equation to solve this.
