Question

Joanie rolls two 1-6 number cubes 80 times. is likely she will roll a sum of 4 more than 6 times?

Answer 1

Rolling two 1-6 number cubes give us the sums 2,3,4,5,6,7,8,9,10,11, or 12 so are so are 11 diferents sums.
The likelihood of rolling a sum of 4 is 1/11.
This means that every 11 roles we should get a sum of 4.
If there are 80 roles then 80/11 ~ 7.27
7.27 times > 6 times

Answer is YES it is likely that she will roll a sum of 4 more then 6 times.
