In a box, there are 8 orange, 7 black and 6 white balls. If one ball is picked up randomly. What is the probability that it is neither orange nor white?
A. 2/3
B. 3/4
C. 7/19
D. 8/21

• QUESTION IS WRONG .THERE SHOULD BE neither "BLACK" nor white?
  then the ans will be come 8/21
  .because total balls are 21
  and neither black nor white .
  so favor case will be only 8C1
  and total case 21C1
  probability will be 8C1/21C1=8/21
  
  
  
  
  and if we solve the question according to the neither orange nor white
  then ans will be 7C1/21C1=1/3
  and this is not option
