The probability of drawing at least 1 male in a sample of 4 participants, given that half of the participants are male and half are female, can be calculated by subtracting the probability of drawing no males (all females) from 1. The probability of drawing all females is (1/2)^4 = 1/16 = 0.0625. Therefore, the probability of drawing at least 1 male is 1 - 0.0625 = 0.9375.
