The probability of selecting at least 3 males out of 8 students from a class of 20 (8 males and 12 females) can be calculated using the complementary probability of selecting 0, 1, or 2 males. The complementary probability involves calculating the probabilities of these three scenarios and subtracting them from 1. This approach simplifies the calculation, leading to the correct answer of 0.7404, which accounts for the various combinations of selecting at least 3 males in the group of 8 students.
