Question

Two balanced dice are thrown simultaneously. Find the expected value of getting sum of

numbers on the dice.​

Answer 1

Step-by-step explanation:

So when two dice are thrown there are 36 possibilities. Now to get a sum or 7 you have to get 1,6;6,1;2,5;5,2;3,4;4,3. There are 6 favourable outcomes and total number of outcomes are 36. Hence probability will be 6/36=1/6.
