Question 1025260
The probability (without replacement) that both draws are red is {{{(3/6)(2/5) = 6/30 = 6/30}}}.
The probability (without replacement) that both draws are white is {{{(2/6)(1/5) = 2/30}}}.
The probability (without replacement) that both draws are blue is {{{(1/6)(0) = 0}}}.
The event of drawing two balls that are of different color is the complement of the event of drawing two balls of the same color.
==> The probability is {{{1 - 6/30 - 2/30 = 22/30 = 11/15}}}
