Question

A bag of 7 blue marbles, 8 green marbles, 9 yellow marbles. If one marble is drawn from the bag but not replaced, what is the probability of drawing a blue marble then a yellow marble?

My answer is: 7/24 * 9/23 = 63/552 = 21/184
It is impossible to answer your question due to the fact we do not know what color the marble you drew first was. This decreases the odds randomly and cannot be mathematically calculated.
