What's the probability of rolling a prime number on a fair die

50% chance

Step-by-step explanation:

if it's a six-sided die, the options are 2, 3, and 5. that's three numbers out of six, or half (50%)

1/2; 50%

Step-by-step explanation:

Probability is number of desired outcomes/number of total outcomes.

In a fair die, there are 6 total outcomes.

Now, let's find how many desired outcomes there are.

We can do this by naming the prime numbers form 1-6.

Prime numbers are numbers that are divisible by 2 positive integers: 1 and itself.

This means that 1, 4, and 6 are not prime numbers.

The prime numbers are: 2, 3, and 5.

So there are 3 desired outcomes.

That means the probability would be 3/6

This can be simplified to 1/2, or 50%
