A jar holds 6 blue blocks, 8 red blocks, 10 green blocks, if a block is taken from the jar at random and not replaced and then a second block is chosen, what is the probability that you will draw a green and a blue

To find compound probability, multiply the probability of the first and second events. In this case, if you wanted to draw the green first and then the blue, 10/24 or 5/8 times 6/23 equals 30/184 which reduces to 15/92.
