In your sock drawer you have 6 brown socks, 4 black socks and 8 white socks. without looking, what is the probability of you pulling out 2 white socks in a row?
--------------------------------------------
# of pairs of 2 white socks = 8C2 = (8*7)/(1*2) = 28
---
# of random pairs of socks = 18C2 = (18*17)/(1*2) = 153
---
P(2 white socks) = 28/153 = 0.1830
