Question 1141081
<br>
23 total marbles to start; 8 red, 6 green, 9 yellow.<br>
P(yellow first) = 9/23.
Remaining marbles are 8 red, 6 green, 8 yellow.<br>
P(yellow next) = 8/22.
Remaining marbles are 8 red, 6 green, 7 yellow.<br>
P(green next) = 6/21.
Remaining marbles are 8 red, 5 green, 7 yellow.<br>
P(red next) = 8/20.<br>
The probability of that sequence is the product of the probabilities for each marble drawn.
