Answer:

hope it helps

Step-by-step explanation:

On a through of a dice 6 possible outcomes are possible.

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

A die is thrown. What is the probability of getting:

(a) A composite number

(b) A number greater than 3

${\huge{\huge{\underline{\underline{\mathrm{\green{AnsWer:-}}}}}}}$

we all know that a die has 6 numbers

so:-

a)$\frac{3}{6}$(as there are three composite numbers from numbers 1 to 6 that are 1,4,6)

b)$\frac{3}{6}$(as there are 3 numbers after 3 that are 4,5,6.)
