If you have 10 red, 10 blue, 10 orange and 10 black socks in a drawer, how many socks must you pull out of the drawer (assume it is dark and you cannot see the colors) to guarantee that you get two orange socks?

The probability of choose two orange socks from the sock drawer WITHOUT REPLACEMENT:
= P(the first one is Orange) * P(the second one is Orange)
= 10/40 * 9/39 = 3/52.
The odds are barely in your favour bro.
