Question

find the probability of getting a composit number in a dice​

Answer 1

On throw of a dice 6 possible outcomes are possible.

There are { 1,2,3,4,5,6 } . Among which only 4 and 6 are composite numbers i.e. two numbers are composite.

Now from the definition of probability, the probability of getting a composite number on the throw of dice is 1/3 .

so , the answer is 1/3 .
