Question 295554
When calculating probabilities always remember to compare the part the whole. In the original scenario, the "whole" was 300 tosses of the dice and the "part" was 54 fours. So the ratio is 54/300. Theoretically, there are a total of 6 possible tosses (so the whole is 6) and only one chance out of the six to roll a four. So the ratio is 1/6.
Now to find the percent we change each of the ratios into decimals and then into percents:

TO change to a decimal divide--> 54/300= .18 then to change it to percent multiply .18 *100 = 18%
TO change to a decimal divide--> 1/6 = .1666... rounded to .1667 then to change it to percent multiply *100 = 16.67%

Then to find the difference in the percentages just subtract 16.67% from 18% which gives the answer 1.33% or 1 1/3 %
