Question 1153157: In a large statistics course, 70% of the students passed the first exam, 70% of the students pass the second exam, and 62% of the students passed both exams.

Pass at least 1 is Pass(1)+Pass(2)-Pass (1 and 2), because that is double counting that needs to be subtracted.
0.7+0.7-0.62=0.78 overall.
