Q. This season, the probability that the Yankees will win a game is 0.54 and the probability that the Yankees will score 5 or more runs in a game is 0.52 . The probability that the Yankees win and score 5 or more runs is 0.43 . What is the probability that the Yankees will lose when they score 5 or more runs? Round your answer to the nearest thousandth.Answer:
Events Denoted: Let's denote the events as follows:W: The Yankees win a game.R: The Yankees score 5 or more runs in a game.L: The Yankees lose a game.We are given the following probabilities:P(W)=0.54P(R)=0.52P(W and R)=0.43We want to find the probability that the Yankees will lose when they score 5 or more runs, which can be denoted as P(L and R).
Find Probability of Losing: First, we need to find the probability that the Yankees lose a game, which is the complement of the probability that they win. We can calculate this using the formula:P(L)=1−P(W)Substituting the given value for P(W), we get:P(L)=1−0.54P(L)=0.46
Find Probability of Losing and Scoring: Next, we need to find the probability that the Yankees lose and score 5 or more runs. We can use the formula for the conditional probability:P(L and R)=P(R)−P(W and R)Substituting the given values, we get:P(L and R)=0.52−0.43P(L and R)=0.09
Calculate Conditional Probability: Now, to find the probability that the Yankees will lose when they score 5 or more runs, we need to calculate the conditional probability P(L∣R), which is the probability of L given R. We can use the formula:P(L∣R)=P(R)P(L and R)Substituting the values we have found, we get:P(L∣R)=0.520.09P(L∣R)≈0.173
Round Final Answer: Finally, we round the answer to the nearest thousandth as requested: P(L∣R)≈0.173 Rounded to the nearest thousandth, P(L∣R)≈0.173
