Here is the problem in it form with chart. The answers are written in and we needed to verify they were correct. We were told they were correct, but I am not getting that answer. I start with 5-0/2 (5)(18). I thought that was first stop and I was way wrong. Not sure how else to do to get the...

That makes sense. So you part 1 I will find the probability of winning 700 and then my answer will be the opposite sign of what I get out?

I understand that part, but for part 1, won't I need the losing distribution? If not do I get do 700/1000 - 2.5 divided by 30 and figure out the percent lower than that for the answer?

Here is the rest of the problem, but not sure where the percentages of the winning came from to even think about the losing.

Would the losing distribution be (-97.5%,70%)?

I started by trying to write a normal distribution function for losing and not sure if that is possible.
