Answer:
The probability of all events occurring is 1
(1/6)+p=1
p=1-1/6
p=5/6
The probability of not rolling 5 is 5/6
Or you could have just said there are five numbers other than 5 out of the six so:
5/6
Hmmm... since both of the numbers are close to each other, I would think it would be D, But since 9 is bigger than 8 I would pick B, likely, because it is most-likely going to happen.
Hope this Helps!
