Remember the "what assumptions are being made" part of question b? Don't make those same assumptions for this one.
Confused.

.47 drank more than usual (1st and 3rd students)
.53 did not consume more than usual (2nd)

If you remove either the 1st or the third student the probability doesn't change.

If I do .47 x .53 = .25

I'm so lost.
