Suppose for students finishing 2A Math that 22% have a math average ≥ 80%, 24% have a STAT 230 mark≥ 80%, 20% have an overall average ≥ 80%, 14% have both a math average and STAT 230 80%, 13% have both an overall average and STAT 230 ≥ 80%, 10% have all 3 of these averages > 80%, and 67% have none of these 3 averages > 80%. Find the probability a randomly chosen math student finishing 2A has math and overall averages both ≥ 80% and STAT 230 < 80%.
