Concept explainers
In a classroom, there are l00 plastic fish in a tub. The tub is hidden from the students’ view. Some fish are green and some are yellow. The students know that there are 100 fish, but they don’t know how many of each color there are. The students go fishing, each time picking a random fish from the tub, recording its color, and throwing the fish back in the tub. At the end of the day, 65 fish have been chosen, 12 green and 53 yellow. What is the best estimate you can give for the number of green fish and the number of yellow fish in the tub? Describe how to calculate this best estimate, and explain why your method of calculation makes sense in a way that a seventh-grader might understand. Is your best estimate necessarily accurate? Why or why not?
