A bag contains 3 red chips, 2 blue chips, and 1 white chip. If 2 chips are chosen from the bag (without replaceent), determine the probability that they are of different colors.
ways to get two different colors
add the probability of each of these.
I will do the first two:
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.
never mind i got it
thank you so much bobpursley!
