What is the probability of rolling an even with one roll of a numbers cube.
The probability is 11/21.
depends on how many of the even numbers you have
1/2
Even numbers: 2, 4, 6, the probability to get an ven number is 3/6 = 1/2 The probability to get 4 even number in a row is then (1/2)4 = 1/24 = 1 / 16 It is the same probability to get 4 odd numbers (1,3,5) in a row
If two dice (not dices!) are thrown then the probability that you get an even number on one die is 27/36 = 3/4
The sample space is 62 or 36. Take the 1st die rolled. It must start with a 2, 4, or 6. Likewise, the 2nd die rolled must be a 2, 4, or 6. So, with the 1st die at 2, the 2nd die could be 2, 4, or 6. The same holds true for the 4 & 6. There are 9 possible rolls then that are even & even. The probability is 9/36 or 1/4.

The probability is 5/16 = 0.3125
Thereare 50 odd numbers and 50 even numbers in that range, so the probability is 1 out of 2
1/2
The probability is .5 since half the numbers are even and half are odd.
Even numbers: 2, 4, 6, the probability to get an ven number is 3/6 = 1/2 The probability to get 4 even number in a row is then (1/2)4 = 1/24 = 1 / 16 It is the same probability to get 4 odd numbers (1,3,5) in a row
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.
A die has 6 sides with the numbers 1,2,3,4,5 and 6. Three of those numbers are even. So the probability of rolling an even number is 3 out of 6, or 1 out of 2.
