I need the steps for 27

7/20

Step-by-step explanation:

This is a dependent event, which means the first event will affect the probability of the second event.

First, you need to find the probability of the first event, in this case, 3/5 (this is because out of 25 marbles in total, there are 15 blue ones. 15/25 reduces to 3/5).

Now you need to find the probability of the second event, which changes because you have already taken a blue marble out of the bag. So instead of having 15 blue marbles, you now have 14. And instead of 25 total marbles, you now have 24. 14/24 reduces to 7/12.

Now that you have both probabilities, you just need to multiply.

3/5 x 7/12 = 7/20.

So 7/20 will be your final answer.
