Answer to Question #4665 in Statistics and Probability for Elizabeth
A bowl contains 27 M&M candies; 9 are red, 6 are green, and 12 are blue. A piece of candy is chosen, and its color is noted. Suppose you took 3 pieces of candy without looking. Define the event E: Each color is represented. What is P(E)?
Round your answer to 3 decimal places.
Let RGB& be the event that the first candy was red, the second was blue, and the third was red. Similarly, define the events RBG, GRB, RBG, BRG, BGR Then these events are inconistent each with other and& E& is their union, so P(E) = P(RGB) + P(RBG) + P(GRB) + P(RBG) + P(BRG) + P(BGR)
