Final answer:
The probability that Debra's team will win tomorrow is 0.49.
Step-by-step explanation:
To find the probability that Debra's team will win tomorrow, we need to consider the chance of calm days and windy days. Since tomorrow there is a 30% chance of high winds, there is a 70% chance of calm days.
On calm days, the team has a 70% chance of winning and on windy days, they have a 50% chance of winning. Therefore, the probability of winning tomorrow can be calculated as:
Probability of winning = (Probability of calm day) * (Probability of winning on calm day) + (Probability of windy day) * (Probability of winning on windy day)
Probability of winning = 0.7 * 0.7 + 0.3 * 0.5 = 0.49
Therefore, the probability that Debra's team will win tomorrow is 0.49.
