Quizplus · Accepted Answer

The probability that a student faced a disciplinary action and went on to college is found by multiplying the probability of facing a disciplinary action (30% or 0.30) by the probability of going to college given that they faced a disciplinary action (40% or 0.40). Thus, 0.30 * 0.40 = 0.12.
