An experiment was conducted where two dice were rolled 50 times. The sum of the faces are recorded in the chart.

What is the experimental probability of rolling an 8?
Responses
A 12%12%
B 14%14%
C 16%16%
D 18%18%
Question 2
What is the theoretical probability of rolling an 8, and how do the experimental and theoretical probabilities compare?
Responses
A The theoretical probability is 11.1%. The experiment rolled more 8's than would be expected theoretically.The theoretical probability is 11.1%. The experiment rolled more 8's than would be expected theoretically.
B The theoretical probability is 16.7%. The experiment rolled less 8's than would be expected theoretically.The theoretical probability is 16.7%. The experiment rolled less 8's than would be expected theoretically.
C The theoretical probability is 13.9%. The experiment rolled more 8's than would be expected theoretically.The theoretical probability is 13.9%. The experiment rolled more 8's than would be expected theoretically.
D The theoretical probability is 19.4%. The experiment rolled less 8's than would be expected theoretically.

Can't answer part 1, since we don't have the data.

for part 2 ....

ways to get a sum of 8: 2,6 3,5 4,4, 5,3, 6,2 , which is 5 way
prob(a sum of 8) = 5/36 = .13888...
or 13.9%
Correct! The theoretical probability of rolling an 8 is 13.9%.
then why didn't you answer it ???
I apologize for the confusion. You are correct. The answer to part 2 is C. The theoretical probability is 13.9%, and the experiment rolled more 8's than would be expected theoretically.
