Question

Ed intends to roll a six-sided number cube 100 times. What probability model can he use to predict whether or not each roll will give a result that is a composite number?
A. Each roll has a 0.117 probability of being composite
B. Each roll has a 0.333 probability of being composite
C. Each roll has a 0.5 probability of being composite
D. Each roll has a 0.667 probability of being composite

Answer 1

The answer is Each roll has a 0.333 probability of being composite.

(I just took the test, B was the answer)

Answer 2

I think that it would be B. .333, because a dice only has 2/6 composite numbers, 4 and 6, and when you simplify that, it comes out to 1/3, which is equal to .333. I hope that this helped!!!
