varun singh  (11 years ago)

no.of ways of getting 2 gloves(pair)form total(14+20+18=52) is 52c2=1326
no. of ways of getting 2 red gloves from 14 red gloves is 14c2=91.
no. of ways of getting 2 blue gloves from 20 blue gloves is 20c2=190.
no. of ways of getting 2 green gloves from 18 green gloves is 18c2=153.
so the total no of ways =91+190+153=434.
so the required probability is =434/1326=0.327 [answer]

14c2 for selecting 2pair of red gloves
similarly for blue and green
so 14c2+20c2+18c2/52c2=.33

Is this solution Helpfull? Yes (2) | No

1/3
selection of the glove pair of same color will depend on the probability of color getting chosen...and since each color has 1/3 probabaility so the ans wud be 1/3. (internal ways of selecting wont matter as the gloves are identical)
