The answer would really depend on how many numbers are on the cube.  If the cube is numbered 1-6 then the answer two your first question would be  2 out of 6 or 1/3..

The second answer would be  4 out of 6, or 2/3

The third answer would be 3 out of 6 or 1/2

If there were 8 numbers on the cube the answer would change. You simply place the numbers you might roll over the total of all possible numbers.

1.) The probability that you'd roll a 2 or 4 on a dice would be 2/6 or 1/3. You have 6 total faces and 2 numbers you want to roll.

2.) There are 3 even numbers between 1 and 6, and if you also include the number 1, you have 4 options out of 6 or 2/3 probability.

3.) There are 3 odd numbers between the numbers 1 and 6, and a total of 6 faces. The probability that you'll roll an odd number is 3/6 or 1/2.

1) There is about numbers from 1-6 on the dice, and you have 2 or 4, so your probablity should be 2/6= 1/3

2) There is 3 even numbers 2, 4 and 6 and the other number 1 so the probablity should be 4/6=2/3

3) There is 3 odd numbers so probablity rate should be 1/2

The probability of it being a two or four is a two out of six chance or 1/3 chance.

The probability of an even number or 1 would be four out of six chance or a 2/3 chance.

The probability of an odd number would be 1/2 or 3 out of 6
