Answer 1

Answer #1

There are 36 output we can get if we throw two dice , out of it we can get sum is equal to 4 if we get the following combinations

(1,3),(2,2),(3,1)

So if we roll two dice then the probability of getting the sum equal to 4 is p=3/36

so to get expectaion of 4 in n=180 times is n*p that is

180*(3/36)=15 answer
