A person took out jacket and gloves, which are available in blue 16, yellow 40 and red 36.If the power goes off and he can distinguish between gloves and jacket but not in colors. What's the possibility that he will pick up pair of gloves of each color.

• total 16+40+36=92 so selecting 2 out of 92---> 92C2,pair of same colour means 16C2+40C2+36C2=3060,92C2=8372=======>3060/8372=0.3655 is da prabability..

• take two maximum values ie... 40+36=76+2=78

• take the maximum no. of jackets & gloves & add them,i.e. 40+36=76. Now add 2 to the sum (since pair of each is required)so 76+2=78is the ans.

• in this case we have to select pair of gloves of each colour so the no of outcomes will be 16c2+40c2+36c2=1530
  and total no of outcomes will be 96c2=4186
  so probability will be 1530/4186=0.3655 is the answer
