Question

Two 6 sided dice are rolled what is the probability that the sum of the two numbers on the dice will be 4

Answer 1

1/12

Explanation:

There are 3 ways to roll a sum of 4: 3 on the first die and 1 on the second die, 2 on the first die and 2 on the second die, and 1 on the first die and 3 on the second die. There are 36 total possibilities, so the probability is 3/36 = 1/12.

Answer 2

proablity=disired outcomes/total possible
find desired

find wwhat adds to 4
2 and 2
2 and 2
1 and 3
3 and 1


4 desired outcomes
total possible=6*6=36

4/36=1/9

proablity is 1/9
