If you select 4 Jelly beans you are guarenteed that you will
have 2 that are the same color.

Answer / miller

Pick 4 ... There are 3 colors so if i pick 4 surely i will repeat one color once or more than once.

Answer / aspire

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!)

Hope easy to follow!
