Final answer:
The experimental probability of not landing on a 6 can be found by subtracting the number of times the number 6 was rolled from the total number of rolls and then dividing by the total number of rolls.
Step-by-step explanation:
The experimental probability of not landing on a 6 can be found by subtracting the number of times the number 6 was rolled from the total number of rolls and then dividing by the total number of rolls. In this case, the number cube was rolled 24 times and landed on the number 6 three times. So the number of times the number 6 was not rolled is 24-3 = 21. Therefore, the experimental probability of not landing on a 6 is 21/24.
