- 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] - 12 years agoHelpfull: Yes(42) No(2)
- solve this u get answer = (14c2+20c2+18c2)/52c2)
Final answer is 0.327 - 12 years agoHelpfull: Yes(10) No(0)
- 4/52

- answer should be
(14c2 *20*18)/52c2

- 14c2 for selecting 2pair of red gloves
similarly for blue and green
so 14c2+20c2+18c2/52c2=.33 - 12 years agoHelpfull: Yes(2) No(0)
- 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) - 13 years agoHelpfull: Yes(0) No(6)
