This season, the probability that the Yankees will win a game is 0.61 and the probability that the Yankees will score 5 or more runs in a game is 0.49. The probability that the Yankees lose and score fewer than 5 runs is 0.3. What is the probability that the Yankees will lose when they score 5 or more runs? Round your answer to the nearest thousandth.
Q. This season, the probability that the Yankees will win a game is 0.61 and the probability that the Yankees will score 5 or more runs in a game is 0.49. The probability that the Yankees lose and score fewer than 5 runs is 0.3. What is the probability that the Yankees will lose when they score 5 or more runs? Round your answer to the nearest thousandth.
Define Events: Let's define the events:W: Yankees win a game.L: Yankees lose a game.S: Yankees score 5 or more runs.We know:P(W)=0.61P(S)=0.49P(L and not S)=0.3First, find P(L) using the complement of P(W):P(L)=1−P(W)=1−0.61=0.39
Calculate P(L): Next, calculate P(L or not S) using the complement of P(S):P(L or not S)=1−P(S)=1−0.49=0.51
Find P(L or not S): Now, use the Inclusion-Exclusion Principle to find P(L and S):P(L and S)=P(L)+P(S)−P(L or not S)=0.39+0.49−0.51=0.37
