You have a very messy sock drawer with 3 blue socks, 5 black socks, and 1 white sock. You pick two socks from the drawer. You pick a second one without replacing the first one. Find each probability.
1) Probability of picking 2 blue socks
2) Probability of picking black than blue
I think I have to draw a certain number of blanks and then write in numbers and multiply... I am only uncertain as to what numbers I need to use..
Thanks for your help!

I will be happy to critique your thinking.

For the first one, would I take 3/9 times 2/8 because there is a 3/9 chance of picking a blue sock, but then after picking out one, there is only a 2/8 chance. So the answer for 1 is 6/72 ???

there were 6 purple socks and 4 orange socks in a drawer. Zucky picked one sock without looking and then another without looking(or replacing the first). What is the probability that he picked 2 purple socks?
