Last math question! A bin contains green and orange balls. A ball is selected at random and then placed back in the bin. The results are recorded after 10 trials, 50 trials, and 200 trials. The results are recorded in the table. Based on the table, how many times can you expect that a green ball will be selected in 500 tries?

OpenStudy (myth1111):

Can you make a screenshot of the table or something?

OpenStudy (anonymous):

I don't know how to screen shot /: I am new to this

@zer0_ Im in 7th grade k 12 too!

OpenStudy (anonymous):

its easy if you read the lesson.

OpenStudy (anonymous):

the way to figure out the answer is you figure out what number can be divided by 62 and equal to .2 so it would be 310 because 62 / 310 = .2

OpenStudy (amberparrishxo):

@NMVA is correct. It is 310.
