ways to get two different colors

rb

rw

bw

br

wr

wb

add the probability of each of these.

I will do the first two:

Pr(rb)=3/6*2/5

Pr(rw)=3/6*1/5

ok but how do i find the final probability?

i see how i can get the probability of a certain combination, but i don't understand how i can find that end probability.
