In a box there are 3 pink, 5 black, and 9 yellow flowers. One flower is picked up randomly. What is the probability that it is neither pink nor black?
Total number of flowers = 3 + 5 + 9 = 17 Let E= event that the flower drawn is neither pink nor black = event that the flower drawn is yellow. n(E) = 9 P(E) = 9/17
