Richard took a handful of pencils from a large box. Out of 15 pencils in his hand 4 was glittery. How many glittery pencils should Richard expect

Answer: Well since we don't know the exact number of pencils in the box, it will be a guess. But 4 glittery pencils in a group of 15 is 3.75 %. So Richard should expect approximately 1/4 of the pencils to be glittery.
