- number of jelly beans of each color is not mentioned thus let us assume there are x red beans y blue beans and z green beans
let the minimum of x y and z be min
if we grab min+1 beans then we can have 2 of the same color even if all others are different - 12 years agoHelpfull: Yes(2) No(5)

First 3 might be different, but fourth one will be the second bean of any one of the color for sure. - 10 years agoHelpfull: Yes(0) No(0)

there are three different colors

by picking 4 we will have definitely of the same kind either of the four. - 10 years agoHelpfull: Yes(0) No(0)
- if red>>blue>>green than we have to grab at least no of blue + green so that only one color left and the next 2 jelly would be the same color..

- count the number of beans in each color first. say RED=25, BLUE = 35, GREEN = 45.
IF YOU WANT RED :
Now if you pick 45, worst situation is all 45 are GREEN;
then pick 35 the worst situation is all 35 are BLUE ;
next pick 2 and you will surely have 2 RED!
IF YOU WANT BLUE :
Pick 45 : worst - all GREEN
Pick 25 : worst - all RED
Pick 2 more : sure BLUE
Same way for GREEN too (Pick 25 and 35 and then 2 more!) - 6 years agoHelpfull: Yes(0) No(0)
