If the "number cube" you are referring to is what we normally call a die (one of a pair of dice), the chances of tossing an 8 are nothing since the cube has only 6 sides and is numbered 1 to 6.
If a "number cube" is something else, perhaps someone else can answer the question.
1/6
(1/2)^3 = 1/8th Since the initial probability (assuming independence) of getting a head in a single toss is one half (1/2) we just cube this probability because of the number of events we are performing. So if you were to try to calculate the probability of a coin being tossed 6 times it would be one half to the 6th power which is 1/64.
Every number on a number cube is a whole number. (A whole number is a number without a fraction or decimal) So the probability of rolling a whole number on a number cube one time would be 6/6 or 1.
The probability is zero. That means that it can't happen, because there's no '7' anywhere on the cube.

If the cube is uniformly weighted there is a 1 in 6 chance of any side landing face-up

There is only one even number over 4, which is 6, so when rolling the number cube, the chances of it coming up are 1/6.
These are all independent events. So the probability of them all happening is the product of the probabilities of each one of them happening. The desired probability is (2/6)*(1/2)*(1/2)=1/12

The experimental probability of a number cube that lands on 5 four times in a twenty toss trial is Pexp(5) = 4/20 = 1/5 = 0.20 = 20%
The probability is zero. That means that it can't happen, because there's no '7' anywhere on the cube.

For an ordinary number cube, the answer is 1/6
