You roll a standard, six sided number cube. what is the probability of rolling a prime number or a number greater than 2.

Answer 1

1, 2, 3, 4, 5, 6

p greater than 2 = 4/6 = 2/3
p 2 or smaller and prime = 2/6 = 1/3

2/3 + 1/3 = 1

every single side of the cube is either greater than 2 or prime (two and one) so you simply will get the desired result in 100% of your rolls :)

Answer 2

What is the probability of rolling a 5 on a sided number cube

Answer 3

Prime numbers are: 2, 3, and 5.
Numbers that are greater than 2 are: 2, 3, 4, 5, and 6.

Meaning the only number you could get that wouldn't fit the criteria would be 1.

The answer is 5/6

Answer 4

the answer is 2/3. Basically it's saying what is the probability of rolling a number greater than 2. Well, there are 4 possibilities out of 6. Therefore you have a 4/6 chance or 2/3

Answer 5

What about if the number is greater than 4?

Answer 6

If you are looking for the probability of rolling a number greater than 4 on a standard six-sided number cube, there are only two possible outcomes: rolling a 5 or a 6. Both outcomes are favorable, so the probability of rolling a number greater than 4 is 2/6 or 1/3.

Answer 7

What is the probability of rolling a prime number or a number greater than 4

Answer 8

The prime numbers that can be rolled on a standard six-sided number cube are 2, 3, and 5. The numbers that are greater than 4 are 5 and 6. The number 5 appears in both sets, so it only needs to be counted once.

Therefore, the possible outcomes that fit the criteria are 2, 3, 5, and 6. Out of a total of 6 possible outcomes, there are four outcomes that meet the criteria: 2, 3, 5, or 6.

So, the probability of rolling a prime number or a number greater than 4 is 4/6 or 2/3.
