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.

1 answer

To predict how many times the number 9 was rolled, we need to first calculate the probability of rolling a 9.

There are a total of 6 possible outcomes on the number cube, and there is only 1 outcome that is a 9. Therefore, the probability of rolling a 9 is 1/6.

To predict how many times the number 9 was rolled in 246 rolls, we 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 was rolled approximately 41 times out of 246 rolls.
