The probability that Luis will pass his statistics test is 0.73 . Find the probability that he will fail his statistics test. A. 0.27 B. 1.37 C. 0.37 D. 2.70

Step 1 ：The probability of an event happening and the same event not happening are complementary. This means that their probabilities add up to 1. Therefore, to find the probability that Luis will fail his statistics test, we subtract the probability that he will pass from 1.

Step 2 ：Given that the probability that Luis will pass his statistics test is 0.73.

Step 3 ：Subtract the pass probability from 1: \(1 - 0.73 = 0.27\)

Step 4 ：Final Answer: \(\boxed{0.27}\)
