Question

Two dice are thrown at the same time. Find the probability that the sum of the two numbers appearing on the top of the dice is: 

8

Solution

The number of possible outcomes =`6xx6=36` 

The outcomes favourble to the event the sum of the two number is 8=E={(2,6),(3,5),(4,4),(5,3),(6,2)}` 

The number of outcomes favourable to E= n(E) = 5 

Hence, `p(E)=(n(E))/(n(S))=5/36` 

  Is there an error in this question or solution?
