During the first three semesters of studies, 40% of EMU COB students take ACCT1. Given that an EMU COB student takes ACCT1 during the first three semesters, the chances are 35% that he/she takes then STAT1. Furthermore, 69% of the students take at least one of the two courses during their first three semesters. What is the probability that a randomly selected EMU COB student takes STAT1 during the first three semesters?
