@supersmart1001 Can you help?

OpenStudy (mathstudent55):

The probability of choosing an item is the number of items you are interested in divided by the total number of items. When you have two drawings, you multiply the probabilities.

OpenStudy (mathstudent55):

For the first drawing, you want a blue marble. How many blue marbles are there? How many total marbles are there?

OpenStudy (mathstudent55):
