A number cube is rolled 300 times and the results recorded: 48 ones, 53 twos, 42 threes, 51 fours, 50 fives, and 56 sixes. What is the experimental probability of NOT rolling a five?
The total number of rolls is 300, and there were 50 fives rolled. Therefore, the number of times a number other than five was rolled is:
300 - 50 = 250
The experimental probability of NOT rolling a five is:
250/300 = 5/6
Therefore, the experimental probability of NOT rolling a five is 5/6 or approximately 0.8333.
