There are three green, three blue and three white marbles in a jar. what is the probability of drawing first a white marble and then a blue marble, without replacing the first marble into the jar?

The probability of first drawing a white marble is 3/9. Once you've drawn it, the probability of drawing a blue marble is 3/8. So you multiply the fractions and get 9/72 as your answer. You can simplify to 1/8 if you'd like. Hope this helps!

Yep u would so yeah
