Answer 8

Actually, I'd have to give "exponential probability distirubutions" a thorough review before I could be of any significant help to you. What learning materials are y ou using at the moment? Book, notes? Internet searches?

Answer 9

I am using my instructors lecture notes and examples.

Answer 10

well power point lecture slides

Answer 12

yeah no worries. have a good day
