Question

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?

Answer 1

If he selects a pencil at random, he would be least likely to select a blue pencil because there aren't as many blue pencils compared to the rest. 

Answer 2

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.
