Terry has a number cube that is numbered from 1 to 6. She rolls the cube 50 times. Which equation can be used to predict the number of times that she will roll a number that is greater than 4?
A number cube is rolled 160 times the number 2 comes up 39 times what is the experimental probability of rolling a 2 what is the theoretical probability or rolling a 2

To predict the number of times Terry will roll a number greater than 4, we can use the equation for probability.
The number cube has 6 sides, and each side has an equal chance of being rolled.
The probability of rolling a number greater than 4 is 2 out of 6, or 2/6. Simplifying this fraction gives us 1/3.
To predict the number of times Terry will roll a number greater than 4, we can multiply the total number of rolls (50) by the probability (1/3).
So, the equation that can be used to predict the number of times Terry will roll a number greater than 4 is:
Number of rolls = Total number of rolls × Probability
Number of rolls = 50 × 1/3
Number of rolls = 50/3
Number of rolls ≈ 16.67
Therefore, she is expected to roll a number greater than 4 approximately 16 times.
