There are 10 chips altogether. 4 of them are white.
4/10 is the chance of lifting out a white chip
There are 3 of them left and 9 chips altogehter.
4/10 * 3/9
12/90
4/30
2/15
Comment
(my edit) it is not that 2/15 is wrong (although it is not entirely right).
1/3 is the correct answer if you assume that what happened during the first draw has nothing to do with what will happen on the second. It is like saying if you throw 11 heads in a row with a fair coin, what are the chances of throwing a heads on the 12th throw? The answer is 1/2. That is the same kind of question you have asked.
The two of us who have responded have really responded to what are the chances of drawing 2 white chips. The question really does not restrict us in a way that prevents us from saying that. I'll stick with
B <<<< answer
but I think it would be nice if the writer of the question made it clear that 1/3 should be the proper answer. I am glad you came back and posted the right answer. It makes me think.
The semi right answer is B <<<<----
If my reasoning bothers anybody, I'll reedit again. I'm only leaving it because sometimes a mistake is more instructive than a given answer.
Answer:
I'm not sure but the last one I think is wroght
Your question is very confusing but x=8 so just plug in 8 where you see X
Answer:
I promise you this is easier than it looks, just bare with me.
You have to order these numbers from the smallest to the biggest. Now before we do this, we wanna make the fractions and mixed numbers decimals to make this easier.
5 8/11
Convert the fraction to a decimal: Divide the numerator by the denominator. (8 divide by 11).
Add this decimal number to the whole number part of the mixed number. (0.72 plus 5)
It would be 5.72
Now 57/10
The same steps as the last one, but since it isn't a mixed number you don't add anything. (57 divided by 10)
It would be 5.7
Now we have to order them from least to greatest. How do we figure that out? Well lets list the numbers that we have now:
5.72
5.7
5.67
5.726
Now since they all have the same whole number, we just have to look at the numbers after the decimal. Well the least number we have here is "7". Then it would be 67, then 72, then 726.
So the answer would be from least to greatest:
5.7
5.67
5.72
5.726
I hope this helps..sorry if I took so long I wanted to make sure I explained this as good as I can so you don't keep struggling. Good luck, take care <3
Have a good night/day (:! Much love!
aound 15 or it depends how many slices there were in the first place
