Question

Keith has a bag of gems. He draws a gem, records its tyoe, and puts it back. He repeats this 15 times. He draws 3 rubies, 6 emeralds, 4 sapphires, and 2 diamonds. Make a prediction for the number of diamonds there are in the bag of gems if there are only 90 gems in total in the bag.

Answer 1

Based on the proportions of the gems that were drawn, we can estimate that there are approximately 10 diamonds in the bag of gems. This estimation is obtained by multiplying the total number of gems in the bag (90) by the proportion of diamonds drawn (2/15) to get 12, and then rounding down to the nearest whole number.

Answer 2

So, the answr is 12?

Answer 3

Yes, that is correct. Based on the proportions of gems drawn from the bag, we predict that there are approximately 12 diamonds in the bag of 90 gems.
