Question 13 3 pts We have an urn with 3 red balls and 4 yellow balls. We play a game with the urn and a fair coin as follows: We randomly select a ball from the urn. If the ball is red then the coin is flipped twice; if the ball is yellow, the coin is flipped one time. Define a random variable X = the number of heads obtained, so that X = 0, 1 or 2. If P(X) denotes the probability function for X, find P(0). O 11/28 O 7/18 O 7/20 O 1/3 O 1/4
