The probability to pick out a pink marble is 3/10 because there are 3 pink marbles in a bag of 10 marbles.
The probability to pull out another without putting the first one back in would be 2/9. This is because there are now only 2 pink marbles and 9 in all.
The probability for both of these event to occur will be..
3/10 x 2/9 = 1/15
answer: 1/15
