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 0.43 . The probability that the Yankees win and score 5 or more runs is 0.36 . What is the probability that the Yankees will lose when they score fewer than 5 runs? Round your answer to the nearest thousandth.Answer:
Denote Events: Let's denote the events as follows:W: The Yankees win a game.S: The Yankees score 5 or more runs in a game.We are given the following probabilities:P(W)=0.61P(S)=0.43P(W and S)=0.36We want to find the probability that the Yankees lose and score fewer than 5 runs. Let's denote this event as L (Yankees lose) and F (Yankees score fewer than 5 runs).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)
Calculate Probability of Losing: Now, let's calculate the probability that the Yankees lose a game: P(L)=1−P(W)P(L)=1−0.61P(L)=0.39
Calculate Probability of Scoring Fewer Runs: Next, we need to find the probability that the Yankees score fewer than 5 runs. This is the complement of the probability that they score 5 or more runs. We can calculate this using the formula:P(F)=1−P(S)
Calculate Probability of Losing and Scoring Fewer Runs: Now, let's calculate the probability that the Yankees score fewer than 5 runs:P(F)=1−P(S)P(F)=1−0.43P(F)=0.57
Round Final Answer: To find the probability that the Yankees lose and score fewer than 5 runs, we need to use the Multiplication Rule of Probability for independent events. However, we must first ensure that the events L and F are independent. Since we are not given any information about their dependence, we will assume they are independent for this calculation. The formula is:P(L and F)=P(L)×P(F)
Round Final Answer: To find the probability that the Yankees lose and score fewer than 5 runs, we need to use the Multiplication Rule of Probability for independent events. However, we must first ensure that the events L and F are independent. Since we are not given any information about their dependence, we will assume they are independent for this calculation. The formula is:P(L and F)=P(L)×P(F)Now, let's calculate the probability that the Yankees lose and score fewer than 5 runs:P(L and F)=P(L)×P(F)P(L and F)=0.39×0.57P(L and F)=0.2223
Round Final Answer: To find the probability that the Yankees lose and score fewer than 5 runs, we need to use the Multiplication Rule of Probability for independent events. However, we must first ensure that the events L and F are independent. Since we are not given any information about their dependence, we will assume they are independent for this calculation. The formula is:P(L and F)=P(L)×P(F)Now, let's calculate the probability that the Yankees lose and score fewer than 5 runs:P(L and F)=P(L)×P(F)P(L and F)=0.39×0.57P(L and F)=0.2223Finally, we round the answer to the nearest thousandth as requested:P(L and F)≈0.222
