Q. This season, the probability that the Yankees will win a game is 00.5454 and the probability that the Yankees will score 55 or more runs in a game is 00.5252 . The probability that the Yankees win and score 55 or more runs is 00.4343 . What is the probability that the Yankees will lose when they score 55 or more runs? Round your answer to the nearest thousandth.\newlineAnswer:
  1. Events Denoted: Let's denote the events as follows:\newlineW: The Yankees win a game.\newlineR: The Yankees score 55 or more runs in a game.\newlineL: The Yankees lose a game.\newlineWe are given the following probabilities:\newlineP(W)=0.54P(W) = 0.54\newlineP(R)=0.52P(R) = 0.52\newlineP(W and R)=0.43P(W \text{ and } R) = 0.43\newlineWe want to find the probability that the Yankees will lose when they score 55 or more runs, which can be denoted as P(L and R)P(L \text{ and } R).
  2. 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:\newlineP(L)=1P(W)P(L) = 1 - P(W)\newlineSubstituting the given value for P(W)P(W), we get:\newlineP(L)=10.54P(L) = 1 - 0.54\newlineP(L)=0.46P(L) = 0.46
  3. Find Probability of Losing and Scoring: Next, we need to find the probability that the Yankees lose and score 55 or more runs. We can use the formula for the conditional probability:\newlineP(L and R)=P(R)P(W and R)P(L \text{ and } R) = P(R) - P(W \text{ and } R)\newlineSubstituting the given values, we get:\newlineP(L and R)=0.520.43P(L \text{ and } R) = 0.52 - 0.43\newlineP(L and R)=0.09P(L \text{ and } R) = 0.09
  4. Calculate Conditional Probability: Now, to find the probability that the Yankees will lose when they score 55 or more runs, we need to calculate the conditional probability P(LR)P(L | R), which is the probability of LL given RR. We can use the formula:\newlineP(LR)=P(L and R)P(R)P(L | R) = \frac{P(L \text{ and } R)}{P(R)}\newlineSubstituting the values we have found, we get:\newlineP(LR)=0.090.52P(L | R) = \frac{0.09}{0.52}\newlineP(LR)0.173P(L | R) \approx 0.173
  5. Round Final Answer: Finally, we round the answer to the nearest thousandth as requested: P(LR)0.173P(L | R) \approx 0.173 Rounded to the nearest thousandth, P(LR)0.173P(L | R) \approx 0.173
