A bag contains 12 candies of which 3 are blue . Two candies are chosen from the bag without replacement. What is the probability
° both are blue?
° at least one is blue?
P(blue) = 3/12 * 2/11
P(>= 1 blue) = 1-P(no blue) = 1 - (9/12 * 8/11)
° both are blue?
° at least one is blue?
P(>= 1 blue) = 1-P(no blue) = 1 - (9/12 * 8/11)
