Science philosophy question: Which is a better way to measure?

Here's an opinion question for those of you that like to think and talk about science.
This question is about the detection part of sampling.
Setup: a bowl of 10,000,000 marbles. 1,000 red marbles, and 9,999,000 green marbles.
Which is the more accurate way to get the makeup of the red marble count?
Count all the green marbles?
OR
Count all the red marbles?
Which, given counting error would be the most reliable method when there is likely error present?
Which way to quantify would require counting of the highest resolution?
Which way of counting would you say represents the better way to count?

I'm not doing your homework.

I would advise against putting all your marbles in one bowl
Posted on 8/29/16 at 11:39 am to Pectus
You already know there are 1000 red marbles.
Problem solved

Count all marbles. Divide by blue

Neither your teacher told you the exact makeup

You don't have any marbles. You lost them years ago.

If you are looking for the number of red marbles, it seems pointless to count the green ones.

I would be confused as to why I have a big fricking bowl with 10 million marbles in it. Then I would get a slingshot.

You framed this problem wrong. Don't give the counts of the marbles, but rather the percentages.
And the answer would be to count them both...multiple times.

I'd be more confused by why you decided to eat them.

Using these quanities, and time not being a factor, I would say count the Green marbles.
Counting all of the green marbles ensures that you've not missed any red marbles. It would be much easier to spot a missed green amongst 1000 as opposed to one red amongst 9 million.

There is no answer...
It is only which is easier to count, and which way to count is more reliable?

Why would you need to count the red marbles if you already know you put 1,000 in the bowl?
Posted on 8/29/16 at 11:52 am to Pectus
You count the red marbles.
Posted on 8/29/16 at 12:01 pm to Pectus
Red marbles. The error will be much smaller

Just knowing the % of each, I would get a total volume of the storage container, a volume of one red and green marble (making sure they were the same, then estimate the total count. Multiple by the %, and have my answer.

Weigh the 1,000 marbles
Do the math as if you weighed all the marbles
Then weigh the green marbles, it should be pretty close
