The probability of at least three students planning to volunteer can be calculated using the binomial distribution formula. The probability of success (p) is 0.10, and the number of trials (n) is 30. We calculate the probability of 0, 1, and 2 students planning to volunteer and subtract from 1 to find the probability of at least 3 students. This results in approximately 0.5886.
