To find the probability that a student has at most 2 siblings, we need to add up the probabilities of the first three outcomes in the table: P(0 siblings) + P(1 sibling) + P(2 siblings). This gives us 0.22 + 0.35 + 0.20 = 0.77. Therefore, the best choice is A, with a probability of 0.77. To find the probability that a student has at most 2 siblings, we can add up the probabilities for the first three outcomes (0 siblings, 1 sibling, or 2 siblings). This gives us 0.39 + 0.24 + 0.14 = 0.77. Therefore, the answer is A) 0.77.
