Question

A fair die is rolled find the probility of
getting a primenumber ​

Answer 1

Answer:

3 is the answer, as 1,3, and 5 are prime numbers

Answer 2

Step-by-step explanation:

First doing the questions we would first see the formula to how to calculate probability. This formula is given as follows -

The number of specific outcomes that we want

----------------------------------------------------------------------

         The total number of outcomes.

Now lets start the question.

A dice has 6 digits engraved on it. In this prime numbers are 2, 3 and 5. You must be thinking that 1 is also a prime number but here there is no mention of 1. I must tell you that one is neither a prime number nor a composite number. It is a unique number. So, there are 3 prime numbers on a die. We will now put the values in the formula.

The number of specific outcomes that we want        3            1

----------------------------------------------------------------------  = --------  =  ------

         The total number of outcomes.                          6            2

So the probability of getting a prime number is 3/6. If you want to simplify it then the answer would be 1/2.
