Quizplus · Accepted Answer

The probability of being single or having a college degree is calculated using the formula P(A or B) = P(A) + P(B) - P(A and B). Here, P(single) = 100/600, P(college degree) = 400/600, and P(single and college degree) = 60/600. So, P(single or college degree) = (100/600) + (400/600) - (60/600) = 0.733.
