HELP!!!! PLEASE!!!
A six sided die is rolled 20 times and the number 3 comes up six times. In the next three rounds (the die is rolled 20 times in each round), the number 3 comes up six times, 5 times and 7 times. The experimental probability of rolling a 3 is ? % which is approx. ? % more than its theoretical probability. Round off your answer to the nearest integer.

The experimental probability is the probability of the die returning a value (in this case, 3) verified through the conduct of the experiment. In this case, the experimental probability is the mean of the number of times the number 3 turns up.
The theoretical probability of the die returning the value 3 is the probability that you'd get assuming the die was perfectly unbiased (i.e. what you would expect in an ideal, value-symmetric situation). So in this case, the theoretical probability of getting the number 3 (as with any other number from a six-faced die) is (100/6)% = 16.67%.

@shiraz14 
The experimental probability of rolling a 3  is 17 %  which is approx. 17 % more than its theoretical probability.
Is this correct?
