i really dont know how to solve it, i missed the class for this one and i have no clue. I think i will have to use the z-score table, but it doesnt make sense, and i never had to get a probability of a probability.
any help or hint will be greatly appreciated, Thanks !
p.s. I didnt know where to post my question, so if am posting in the wrong section, i apologize
