You roll a standard, six-sided number cube. what is the probability of rolling a prime number or a number greater than 4?

We are looking for the probability of a number that is prime or greater than 4. To solve for this, we need to figure out what 'prime' is. Prime is a number that cannot be divided into any smaller factors (aside from 1). An example is 11. 11 cannot be divided by any smaller numbers. There are a total of 6 numbers on a six-sided dice. With this information, let's get started! First, we'll find how many prime numbers are before 4, since the question is asking for prime numbers OR a number greater than 4. 2 and 3 are both prime numbers. So far, we have 2/6. Now, we need to count how many numbers are greater than 4 on a dice. 5 and 6 are numbers greater than 4 on a dice. So far on this, we have 2/6. Now, sum up our fractions from the information we've gathered. 2/6 + 2/6 = 4/6. Your answer is 4/6 or 2/3 if simplified. I hope this helps!

5/6, 1 is not considered a prime number. First few prime numbers are 2,3,5,7. A prime number is a number where the only factors of it are 1 and itself.
