A box contains 6 red balls, 7 green balls and 5 blue balls. Each ball is of a different size. One ball is selected and it is found to be red. What is the probability that it is the smallest red ball?

1) 1/18
2) 1/3
3) 1/6
4) 2/3
5) 1/2

• Probability of smallest red ball = 1/6
  Because we need to find smallest among red balls not among all balls

• P(red)=1/3
  p(smallest in red)=1/6
  total probability=1/18

• Answer is 1/6.
  
  
  all are diffrent size ball so no two are of same size and only one ball among the each color of ball is smallest so
  in the case of smallest red ball .
  total red ball is 6 and only one ball is smallest so answer is
  1/6.
