The P of getting a brown marble is 8/15, and the Probability of a purple is 1/15.
To get the Probability of drawing a brown then purple, you simply multiply the probability of getting a brown with the P of getting a purple.

4/25?

anonymous · Answer

well no, cause you would multiply 8/15 times 1/15.
