Plz help A box contains 100 colored chips; some are yellow and some are green. John chooses a chip at random, records the color, and places it back in the bag. John has recorded 57 yellow chips and 19 green chips. Using these results, what is the predicted number of green chips in the box? 25 43 76 81
@Michele_Laino
ok first add 57 and 19
it's 76
great, now divide the number of green chips by 76
0.25
that's right, if you multiply that by 100 you will get the percentage of green chips in the bag which is 25%. Now take your 0.25 value and multiply it by 100 to fin how many green chips are in the bag
100 is the total chips btw
it's 25
correct, good job
so it's a
looks like it
great could you help me another
sure
Sarah rolled a fair six-sided die 24 times. The table below shows the number of times each number was rolled: According to the results in the chart, what is the experimental probability of getting an even number on the die? 9/24 10/24 15/24 16/24
ok first add up the amount of even rolls
what do you mean by that?
what are the even numbers on a dice?
2, 4 , and 6
correct, now look at the corresponding number of times appeared column and add those numbers up.
only the ones corresponding to 2, 4, and 6
4+9+2
15
now divide that by the total rolls
0.625
that's right. The answer wants it in fraction form though so it's 15/24
oh ok thanks
pls medal
ok
