Question

Cards marked with numbers 1 to 25 are placed in a box and mixed thoroughly .One card is drawn at the random from the box . Find the probability of getting a perfect square number.​

Answer 1

Answer:

total no.of cards is 25

therefore n(s)=25

perfect square number between 1 and 25 are

1,4,9,16,25

let a be the probability of getting perfect square square number between 1 and 25.

n(a)=5

p(a)=n(a)/n(s)

p(a)=5/25

if we simplify 5/25 we get 1/5.
