A bag contains 25 tickets, numbered from 1 to 25. A ticket is drawn and then another ticket is drawn without replacement. Find the probability that both tickets will show even numbers.

Explanation

A=shows in 1st drawn An even number ticket


B= shows in 3nd draw An even number ticket


`P(A)=frac{12}{25} `

`P(B / A)=frac{11}{24} `

`therefore P(A cap B)=P(A) times P(B / A)=frac{12}{25} times frac{11}{24}=frac{11}{50}`
