Question 9 • AZ-Common Core Algebra II A
It is easier to find the complement: the only way none of the three lacks a degree is if all three have college degrees. The probability of that is 0.74 × 0.74 × 0.74 = 0.405224. So the probability that at least one does not have a degree is 1 − 0.405224 = 0.594776, or about 0.5948. The correct choice is C, 0.5948.
