Answer 2

Okay, there are six sides on a cube, 3 numbers less than 4, the number 4, and 2 numbers greater than 4. Do you need a further explanation?

Answer 3

yes

Answer 4

is it 1/6

Answer 5

Well...we know there are 6 possible outcomes...of those, how many do we want?

Well we want Greater than 4 .....that is 5...and 6

\[\large P = \frac{\text{Favored Outcomes}}{\text{Possible Outcomes}} = \frac{2}{6} = \space ?\]

Answer 6

No it is not 1/6. There are two numbers greater than 4, that being 5 and 6. If there are two numbers greater than 4 out of six on a dice, what would it be?

Answer 7

I think it is 1/3

Answer 8

Please look at the possible outcomes (whether "good" or not): {1, 2, 3, 4, 5, 6|.
How many of those 6 outcomes is greater than 4? Anonymous-B has already mentioned this.

Answer 9

Kia55, 2/6 can be simplified to 1/3, so you are correct.

Answer 10

is 1>4? No? reject it.

A-B is right on target. Nice work, both of you!
