When two dice are rolled, find the probability of getting a sum of 5or6
sample space for two dice =6^n=6^2=36
getting sum of 5 =(1 4)(23)(3 2) (4 1) will be 4
getting sum of 6=(1 5)(2 4)(3 3)(4 2)(5 1) will be 5
favorable for sum of 5 or 6=4+5=9
probability for sum of 5 or 6 = favorable/sample space
=9/36=1/4
answer 1/4
