• no of pssible outcome=26c2=325
  no of ways of obtaining blue or white chips=7*3=21
  so probability=21/325

• 7c1/26 * 3c1/25=21/(25*26)=21/650

• ANS WILL BE 21/650....SATISH IS CORRECT

• p=n(event)/n(sample)
  p=(7c1*3c1)/26c2
  so p=21/325

• total no. of probabilities=26
  the probability of selecting one blue and white = 7C1X3C1 =21
  total probability is 21/26
