From a bag of 2 red, 3 blue and 2 black balls, a ball is picked out at random. the probability to get the red ball is

  1. 2 over 5
  2. 3 over 5
  3. 2 over 7
  4. 3 over 7

The correct answer is: 2 over 7


    No. of red ball = 2 , no. of blue ball  = 3 and no. of black = 2 .
    Total no. of balls in bag = 7
    The required probability = 2 over 7
    Correct choice = 3 .
