Final answer:
The probability that the Texas sharpshooters score exactly 1 goal is 10.5%.
Step-by-step explanation:
To calculate the probability that the Texas sharpshooters score exactly 1 goal, we need to multiply the probability of scoring the first goal (P(A)) with the probability of not scoring the second goal (1 - P(B|A)). In this example, P(A) = 0.70 and P(B|A) = 0.85.
The probability of scoring exactly 1 goal is:
P(A) * (1 - P(B|A)) = 0.70 * (1 - 0.85) = 0.70 * 0.15 = 0.105.
To convert this probability to a percentage, we multiply by 100:
0.105 * 100 = 10.5%.
