Question

When two dice are thrown simultaneously, what is the probability that the sum of the two numbers that
turn up is less than 11?
​

Answer 1

Answer:

when two dice are thrown simultaneously the sample space is :

S{1,1 1,2 1,3 1,4 1,5 1,6 2,1 2,2 2,3 2,4 2,5 2,6 3,1 3,2 3,3 3,4 3,5 3,6 4,1 4,2 4,3 4,4 4,5 4,6 5,1 5,2 5,3 5,4 5,5 5,6 6,1 6,2 6,3 6,4 6,5 6,6} then the sample point is :

n(S)= 36

Now, event A : to get the sum of two numbers is less than 11

so, the probability will be :

n(P)=n(A)/n(S)

= 34/36

=17/18

therefore, your answer to this question is 17/18
