Question

Quizplus · Accepted Answer

Since half of the students have blue eyes, the probability of each student having blue eyes is 0.5. Using the binomial distribution, the probability that 80% or more of a class of 15 students will have blue eyes is approximately 0.023, which is the highest amongst the given options. The probability decreases as the class size increases, making options B and C even less probable. Therefore, option A is the most probable event.
