Question

Janise rolled a number cube 50 times and recorded the results in this table.

Outcome Number
1 7
2 9
3 8
4 8
5 6
6 12

What is the theoretical probability of the cube landing on a 6? What is the experimental probability of the cube landing on a 6?

A.
Theoretical - 12%
Experimental - 24%

B.
Theoretical - 16.7%
Experimental - 16.7%

C.
Theoretical - 16.7%
Experimental - 24%

D.
Theoretical - 20%
Experimental - 12%

Answer 1

Unfortunately, we don't ACTUALLY know enough about the "Number Cube". If it had said a "Standard Die", rather than the oddly-more-socially-acceptable "Number Cube", we would have had more information. Let's assume the Number Cube is a Standard Die, making all of 1-6 equally probable.

p(6) = 1/6
Experimental Result = 12/50

Create decimal equivalents and you are done.

Answer 2

Ok that you I though something was wrong with not know enough. well thank you.

Answer 3

If you plan to IM me, you'll have to "FAN" me if you want a response in that environment. However, it's fine that I can't IM you, since I woudl MUCH rather communicate here, publicly and where LaTeX works.

12/50 = 0.24 = 24%. What's the question? You need to be fluent in this sort of transformation.

Answer 4

So my answer's A.

Answer 5

That is not correct. Take another shot at p(6) = 1/6.
