For c), you're sampling from a normal distribution.View attachment 31683
I have this sample problem for a normal distribution here. I know how to get those in (a) and (b). But I'm a bit puzzled on how to get (c). An explanation would be enough. Thank you!
As for "at least 2", you should have learned that that sort of question can commonly be solved by restating "at least 2" as "not 0 or 1". Have you learned about the binomial distribution?View attachment 31683
