Answer: P(getting total < 7) = 1/4
Explanation:
#1 = 1,2,3,4,5,6
#2 = 1,2,3,4,5,6
There are 36 ways to roll 2 dice in total.
Roll to get total less than 7:
1 + 1 = 2
1 + 2 = 3
1 + 3 = 4
1 + 4 = 5
1 + 5 = 6
2 + 2 = 4
2 + 3 = 5
2 + 4 = 6
3 + 3 = 6
There are 9 ways to roll 2 dices and get total of less than 7
So the probability can be written:
9/36 = 1/4
