- 20 blue, 18 green and 14 red gloves are there
Here we need to select 2 such that they are of the same colour
This can be done in 20C2 + 18C2 + 14C2
Total cases = 52C2
Required probability = (20C2 + 18C2 + 14C2)/52C2 - 10 years agoHelpfull: Yes(19) No(1)
- 20C2 + 18C2 + 14C2
Total cases = 52C2
probability = (20C2 + 18C2 + 14C2) / 52C2 - 10 years agoHelpfull: Yes(3) No(1)
