Is rolling an even number on a number cube an event or outcome?
Before you roll the cube it is an even. Afterwards, it is an outcome.
How many even number are in the cube?
Since there is no cube, the answer must be 0.
What is probability of rolling a number divisible by 2 on a number cube?
Well, numbers divisible by 2 are even numbers, and the even numbers from 1 to 6 are 2,4,and 6. Since there are 3 out of 6 even numbers on a number cube, there is a probability 1/2 to roll an even number on a number cube.
What is the probability of rolling an odd number or an even number on a number cube?
A standard number cube has numbers 1-6, so there's a 50% (or one-half) chance of rolling both an odd or even number.
What is the probability of rolling a 4 or an even number on a number cube?
That depends on how many sides the cube has but if it was a 6 sided cube then the probability of getting a four is 1 to 6 and even is 3 to 6. Since 4 is even, then the result set of 4 intersect with the result set of even, so the probability of rolling a 4 or an even number is 1 in 2, or 0.5.
