$\large{\underline{\underline{\bold{\pink{\sf{Prime\:no.}}}}}}$

The numbers that are divisible by 1 and the number itself are known as Prime Numbers..For Eg:. 2 5 7 etc..

$\large{\underline{\underline{\bold{\green{\sf{Even\:No.}}}}}}$

The numbers that are divisible by 2 are known as Even numbers..For Eg:. 2,4 8,28 etc.

→Prime no. between 1 to 25 are :.

→2, 3, 5, 7, 11, 13 , 17 ,19 ,23

a) One digit numbers are :.

↦2, 3, 5, 7 (Total = 4)

↦Probability → $\frac{No.\:of\:fav.\:outcomes}{Total\:no.\:of\:outcomes}$

↦$\frac{4}{9}$

b)Even number:.

↦2 (Total = 1)

Probability → $\frac{No.\:of\:fav.\:outcomes}{Total\:no.\:of\:outcomes}$

↦$\frac{1}{9}$

c) Odd numbers:.

↦3 , 5, 7, 11 , 13 , 17 , 19 , 23 (Total=8)

↦Probability → $\frac{No.\:of\:fav.\:outcomes}{Total\:no.\:of\:outcomes}$

↦$\frac{8}{9}$

d)No. greater than 11:.

↦13 ,17 ,19 , 23 (Total = 4)

↦Probability → $\frac{No.\:of\:fav.\:outcomes}{Total\:no.\:of\:outcomes}$

↦$\frac{4}{9}$
