Answer:

60 red marbles

Explanation:

If John picks 10 marbles and 6 of them are red, there is a 60% chance of pulling out a red, which also means 60% of the total number of marbles are red.

(To be fair, 10 marbles is not a lot to base an estimate on, but I digress.)

Therefore, if there is a total of 100 marbles in the bag, 60% of 100 is 60. Our estimate will be 60 red marbles.

Answer:

60 red marbles

Explanation:

10 marbles are taken out of the bag.

6 marbles taken out are red.

So the other 4 marbles taken out are blue.

200/4 = 50

50 is close to 60.
