Problem 68 of 7
Find the missing conditional probability from joint and marginal probabilities P(X and Y)=0.06 and P(Y)=0.20.
Using a hint is okay. It just tells the trainer to give you a little more review.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Write the multiplication rule with the requested condition direction.
2. Substitute joint and marginal probabilities.
3. Divide to solve for the conditional probability.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Dividing by the target event instead of the condition event.
