Question

You get to roll a die one time. if you roll an odd number, you win $3. If you roll a 6, you win $10. If you roll any other number, you loose $4. find the expectation of this game?

Answer 1

1 = $3
2 = -$4
3 = $3
4 = -$4
5 = -$4
6 = $10

3 - 4 + 3 - 4 - 4 + 10 = 4

I believe you take 4/6 = .67 gain

I may be way off on this one.

Answer 2

thank you i have many more to come
