Question 892629: Two students are registered for the same class and attend independently of each other, student A 70% of the time and student B 60% of the time. The teacher remembers that on a given day at least one of them is in class. What is the probability that student A was in class that day?
I tried .366 and that came up wrong. Answer by LinnW(1048) (Show Source):
You can put this solution on YOUR website! The probability that student A is in class is 70%. Whether or not
student B is in class does not affect this since the students
are independent of one another.
