An urn contains different colored marbles. The probability of drawing two green marbles from the urn without replacement is 320 , and the probability of drawing one green marble is 25 .

What is the probability of drawing a second green marble, given that the first marble is green?

Please do not post questions multiple times!

As I have stated elsewhere this is a rubbish question.

Probablilities must be between 0 and 1.

I think this question is probably meant to read:

"*An urn contains different colored marbles. The probability of drawing two green marbles from the urn without replacement is 3/20 , and the probability of drawing one green marble is 2/5 .*

*What is the probability of drawing a second green marble, given that the first marble is green?*"

If so, then:
