Question

Alberto conducted an experiment by rolling a fair six-sided number cube 60 times. He rolled a 2 fifteen times. Which statement about rolling a 2 in Alberto’s experiment is correct?

Answer 1

The experimental probability of rolling a 2 is
`(1)/(4)`.

Explanation:

Since you didn't give any statements, I'll make one myself.

P of rolling a 2 (experimental):
`(15)/(60) =(1)/(4)`

The experimental probability of rolling a 2 is
`(1)/(4)`.

Answer 2

Fair six sided die : fair 6 chances

2 rolled 15 times out of 60 rolls

60/6 = 10

The theoretical probability of rolling a 2 is 10/60 or 1/6.

However, he rolled a 2 15 times out of 60 rolls. That means 15/60 or 1/4.

So, the answer would be: "The experimental probability of rolling a 2 is one fourth and the theoretical probability of rolling a 2 is one sixth.
