Dave 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 at least likely to select

Dave would least likely pick blue
Because blue is the smallest and least number comparing 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.
