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!
