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.
To predict how many times the number 9 was rolled, we need to calculate the probability of rolling a 9 on the number cube.
There are a total of 6 possible outcomes (1, 1, 5, 7, 7, 9) and only one of those outcomes is a 9.
So, 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, it is predicted that the number 9 was rolled approximately 41 times in 246 rolls.
