A 6-sided number cube with the numbers 1, 1, 5, 7, 7, and 9 was rolled 246 times. Predict how many times the number 9 was rolled

Answer 1

Based on the frequencies of each number on the number cube, we can calculate the probability of rolling a 9.

The number 9 appears 1 time on the cube out of a total of 6 possible outcomes. Therefore, the probability of rolling a 9 on a single roll is 1/6.

To predict how many times the number 9 will be rolled in 246 rolls, we can multiply the probability of rolling a 9 by the total number of rolls:

(1/6) * 246 = 41

Therefore, we can predict that the number 9 will be rolled approximately 41 times in 246 rolls.
