Question

A bin contains red balls and purple 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 purple ball will be selected in 400 tries?



Outcome Number of trials
10 50 200
Red 5 36 152
Purple 5 14 48

Answer 5

In experimental probability, the more trials that are done should get a more accurate result. Therefore you should use the proportion given by the 200 trial to find the 400 trial

Do you know how to do that? :)

Answer 6

no?

Answer 7

im stumped :[

Answer 8

what is the proportion of Purple to Total in the 200 trial? :)

Answer 9

67/200?

Answer 10

idk

Answer 11

look at this :) http://prntscr.com/6s5t6z

Answer 12

ohh 48/200

Answer 13

do you divide

Answer 14

then make it into x/400 ;)

Answer 15

48/200=x/400?

Answer 16

96?

Answer 17

there you go ^_^
