prob of blue marble =8/(8+10+6) Now there is a replacement involved so we will have 8/24 * 8/24

there are 24 marbles altogether she has 6 in 24 chances of drawing blue on the first time (write that as a simper fraction) the second time is INDEPENDENT of the first - so the chances are the same both times (she replaces the original blue one) so the chances of 2 independent 6 in 24 events is???
