Yaron has a box of pencils. 5 are green, 12 are brown, 6 are yellow, and 4 are blue. if he selects a pencil at random, which color pencil would he be least likely to select?

Yaron would least likely pick blue because blue is the smallest and least number compared to green, brown, and yellow. 
Blue is 4/27 
Green is 5/27
Brown is 12/27
Yellow is 6/27
and so compared to all of the other fraction too Blue is least likely.

1/5 i hope this
