Answer:
Probability of sum of pips on two faces is at least 9 = 
Step-by-step explanation:
Experiment: Throwing two fair dice.
Total no of Outcome =
= 36
Sample space (list of outcome) is attached.
Let E be the event that sum of pips on two faces is at least 9.

Favorable outcome are where sum is 9 , 10 , 11 and 12.
From Sample space, No. of Favorable outcome = 10
∴ 

1/3
the denonator is 6 because that is the number of numbers there are, and the numerator is 2 because there are 2 numbers less than or equal to 16. you can simplify
Simplies form of 3/8 is 1/4
