find P(X>3.5)

find P(X<5)

**TutorCat**, Wednesday, May 18, 2011 at 1:03amI think there's a mistake with the probabilities were given. 1) probabilities can't be >1 (you get greater than 100% chance). 2) the probabilities don't add up to 1

here is what I think they should be:

.32, .12, .23, .18, .15

P(x>3.5) = probability that a customer selects more than 3.5 items = p(4) + p(5) = .18 + .15

you can do the other one by yourself.
