Hair Type Brown Blond Black Red Wavy 39 6 21 2 Straight 56 17 62 63What is the probability that a randomly selected child will have either brown or blond hair?
Explanation / Answer
Total child have brown hair = (39 + 56) = 95
Total child have blond hair = (6 + 17) = 23
Total number of child = (39+6+21+2+56+17+62+63) = 266
p( Child will have either brown or blond hair) = p( child have brown hair) + p( child have blond hair)
= 95 / 266 + 23 / 266
= 118/266
= 0.44
