Step-by-step explanation:
The probability of an event is the ratio of the number of elements in the event and the number of elements in the sample space.
When a die is thrown, the sample space is S={1,2,3,4,5,6}.
The elements of the sample space that are prime numbers are 2,3 and 5.
The elements of the sample space that are composite numbers are 4 and 6.
There is only one element in the sample space that is neither composite nor prime and that is 1.
Our event is, E: the number obtained is neither prime nor composite.
⇒E={1}.
⇒n(E)=1 and n(S)=6.
⇒P=n(E)n(S)=16.
mark me brilliant answer
