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?
P (number greater than 4) = StartFraction 1 over 6 EndFraction (50)
P (number greater than 4) = StartFraction 2 over 6 EndFraction (50)
P (number greater than 4) = StartFraction 3 over 6 EndFraction (50)
P (number greater than 4) = StartFraction 4 over 6 EndFraction (50)

Numbers greater than 4 are 5 and 6, so 2 out of the 6 faces work.
Probability = 2/6, so expected count = (2/6)·50.
Answer: B (which equals 50/3 ≈ 16.67).
