In a school, the probability of a student wearing spectacles is found to be 0.75. The principal selects a random group of 12 students. Calculate (a) the probability that all 12 students wear spectacles (b) the probability that 10 or more students wear spectacles (c) the conditional probability that all 12 students wear spectacles, given that at least 10 students wear spectacles
