Answer:

Here's what I think the answers are:

Explanation:

First of all, know that all sides of the number cube has a 1/6 chance of landing face up (assuming that it's an unbiased cube).

Rolling a number <7: This means any number from 1-6 (which is all sides of the cube) => 6/6 chances or 100%

Rolling an 8: There's no #8 in a cube with 1-6 numbers in it => 0/6 or 0%

Rolling a number >4: This refers to number 5 & 6. Both of those have 1/6 chance of landing face up so that's 1/6 + 1/6 => 2/6 or 1/3 chance

Rolling a 5: There is one #5 in the cube so => 1/6 chance

Rolling a number other than 6: This refers to number 1-5, where all have 1/6 chance of landing face up. So that's 1/6 * 5 = 5/6

Rolling an even number: There are three even numbers in this cube (i.e., 2, 4, 6). So that's 1/6 * 3 => 3/6 or 1/2

Rolling a number <5: This refers to number 1-4. So, 1/6 * 4 = 4/6 or 2/3

Rolling an odd number: This refers to three odd numbers (i.e., 1, 3, 5). So that's 1/6 * 3 => 3/6 or 1/2

Rolling a number divisible by 3: There are two numbers divisible by 3, which are 3 & 6. So, 1/6 * 2 => 2/6 or 1/3

Order of events:

(9) Rolling a number <7: 6/6

(8) Rolling a number other than 6: 5/6

(7) Rolling a number <5: 4/6

(6) Rolling an even number: 3/6

(5) Rolling an odd number: 3/6

(4) Rolling a number >4: 2/6

(3) Rolling a number divisible by 3: 2/6

(2) Rolling a 5: 1/6

(1) Rolling an 8: 0/6

As you can see, some have the same values, we can't do anything about that; it simply is.

PS To answer that part where they asked "how many of the six possible results...", simply put the numerator. If you include the denominator, that makes it a probability.
