Answer:
2.78%
Step-by-step explanation:
Theres only one number combination you could get for the sum of 2 ( 1 and 1) but there is 36 different outcomes on the 2 dice that you could get for all the numbers.
1/36=.02777.. =.0278 but since its a percentage you move it over 2x to the right from the decimal point which would give you 2.78%
