Drill & Practice # 1

CORRECT!!!!!

6+4+3+2=15;

so there is a 6/15 chance you pull a blue the first time or 2/5;

If you don't replace that marble then there is only 14 left so there is a 2/14 chance of then pulling a purple marble or 1/7;

Then you multiply 2/5 x 1/7 which equals 2/35.

Next Question.
