I hate these, need help . will fan and medal

Answer 1

refer to the table I made you. how many ways to roll and 8? how many ways to roll a 3. add together, divide by 36.

Answer 2

my computer moving slow I was going to post the table but it keeps freezing

Answer 3

possible events for a sum=12,21
No. of events=2
P(sum of 3)=2/36
possible events for a sum of 8=26,35,44,53,62
No. of events=5
P(sum of 8)=5/36
P(sum of 3 or 8)
\[=\frac{ 2 }{ 36 }+\frac{ 5 }{ 36 }=?\]
