ok the five sided solid will have total 25 outcomes
and u can have sum of three(3) by --(2+1)=3 and(1+2)=3 ok
so we can have sum of three by 2
and we can have sum of 8 by-- (3+5)=8 (5+3)=8 (4+4)=8 so total 3 ways right?
so getting a sum of either a 3 or an 8 is possible in=(3+2)=5 ways so your required probability
P=5/25=1/5

D. Probability = 5/25 = 1/5. Total outcomes = 5x5=25, Sum either 3 or 8 has 5 outcomes. so 5/25
