How can we calculate the following probabilities:
1.We rolled 3 dices and the sum is 9
2.We rolled 3 dices and the sum is 10
Thanks in advance.
Hi
The number of events is 6^3 = 216 (some of them giving the same sum).
To get 9 the possibilities are :
6-2-1 : 6 events give this result (621,612,261,216,126,162)
5-2-2 : 3 events give this result
5-3-1 : 6 events give this result
4-4-1 : 3 events give this result
4-3-2 : 6 events give this result
3-3-3 : 1 event give this result
Probability is therefore 25/216 = 11.6 %
