To find the probability of Luis failing his statistics test, we can use the fact that the sum of the probabilities of all possible outcomes is 1. Since passing and failing the test are the only two possible outcomes, we can subtract the probability of passing from 1 to find the probability of failing:
P(fail) = 1 - P(pass) = 1 - 0.49 = 0.51
Therefore, the best choice is A) 0.51.
