There is no way of predicting the amount of marbles inside the bag but to make an educated guess you should: Take 10 viewings 6 times (when the graph on-screen is most accurate) and base your predictions on those results.
E.g.: If the results show 19 blue, 19 red, 19 yellow and 3 green (one of the results I received) my prediction would be 3 blue, 3 red, 3 yellow and 1 green. The way I did this was by dividing each number by 6 (the amount of viewings). 19 divided by 6 is 3.16. 3 divided by 6 is 0.5. I would say that there were 3 blue, 3 red and 3 yellow since 3.16 rounded to the nearest whole number would be 3. I would then say that there was 1 green, since 0.5 rounded up to the nearest whole number is 1 (I did not round it down to 0 since it is evident that the results show that there is at least one green within the bag). 3 + 3 + 3 + 1 = 10. I know that my prediction is valid since all the numbers add up to 10, the amount of marbles within the bag.
By using division and rounding the numbers accordingly you should reach 1000 points.
