Question

What is the probability of getting a sum 9 from two throws of a dice?

Answer 1

Total outcomes=12
Possible outcomes=2(sum of 6&3 and 5&4 =9
Probability=2/12= 1/6

Answer 2

 TOTAL OUTCOMES WHEN DICE IS THROWN 2TIMES, n(S) = (6 x 6) = 36.

Let E = event of getting a sum ={(3, 6), (4, 5), (5, 4), (6, 3)}.

P(E) =4/36
P[E]=1/9
