Question

12 cards numbered 1 to 12 are placed in a box, mixed up thoroughly and then a card is drawn at random from the box. If it is known that the number on the drawn card is more than 3, find the probability that it is an even number. Write any two values which are reflected in the bright students, report card?

Answer 1

E : Number on the card drawn is even 

F : Number on the card drawn is more than 3. 

E = {2, 4, 6, 8, 10, 12}, F = {4, 5, 6, 7, 8, 9, 10, 11, 12} 

E ∩ F = {4, 6, 8, 10, 12}

Values in report card: Good performance through marks and punctuality through attendance.
