The color of the ball is recorded and the ball is put back into the tub. at the end, 7 orange balls and 18 white balls were picked. what is the best estimate you can give for the number of orange balls and the number of white balls 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 un- derstand. is your best estimate necessarily accu- rate? why or why not? 7. in a classroom, there are 100 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 esti- mate, and explain why your method of calcula- tion makes sense in a way that a seventh-grader might understand. is your best estimate neces- sarily accurate? why or why not? 8. there is a bag filled with 4 red blocks and 16 yel- low blocks. each child in a class of 25 will pick a block out of the bag without looking, record the block's color, and put the block back into the bag. each child will repeat this for a total of 10 times. then the child will write on a sticky note the num- ber of red blocks picked. describe a good way to display the data for the whole class. show roughly what you expect the display you suggest to look like, and say why. 9. write several paragraphs in which you describe and discuss some of the misconceptions tha students often have about probability and tha you learned about from the class activities and practice exercises in this section.
