- Probability is : [ 16C2 + 40C2 + 36C2 ]/ 92C2
=>3060 /8372
=> .3655 - 9 years agoHelpfull: Yes(14) No(3)
- possibility= 40+36+2=78
here possibility is asked and not probability - 9 years agoHelpfull: Yes(6) No(5)
- ans= 54
16+36+2=54
- 9 years agoHelpfull: Yes(1) No(2)
- Plz explain it clarityly

- Assuming you need to get the answer to the last question (as per how options are given)
Worst case scenario is she picks up the gloves of a type with the largest count first...
Then, she would pick up 32 red (even) first , then 25 yellow + 1 blue ( to make it even) and finally 2 blue
So, minimum gloves that need to picked = 32 + 25+1 + 2 = 60 - 8 years agoHelpfull: Yes(1) No(0)

- 40+36+2 / 40+36+16 =78/92
78/92=.8847
.8847*100=84.78% - 9 years agoHelpfull: Yes(0) No(1)
- larger no+middle no+2
40+36+2
78 - 9 years agoHelpfull: Yes(0) No(0)
- minimum possibility of finding is : 16(blue) + 36(red) +2(yellow) = 54
- 9 years agoHelpfull: Yes(0) No(0)
- 40+36+1+2= 79
- 9 years agoHelpfull: Yes(0) No(0)
- Probability is (16C2 + 40C2 + 36C2)/ 92C2
- 5 years agoHelpfull: Yes(0) No(0)
