Question

when a number is taken at random from 1 to 9, the probability that it is a square is​

Answer 1

Answer:

Step-by-step explanation:

Let A be an event of having perfect square number from 1 to 10

Perfect square numbers from the numbers 1 to 10 are,

A={1,4,9}

∴n(A)=3

Sample space is written as,

S={1,2,3,4,5,6,7,8,9,10}

∴n(S)=10

∴P(A)=  

n(S)

n(A)

​

 

∴P(A)=  

10
