On the AP Exam (and my test), you are provided with the following two equations:
General Addition Rule
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
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|BC)=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.

"With replacement" means you put the candy back into the bag before you select another one. This makes the two draws independent.
