If the question meant that choosing a marble for five hundred times ; then the calculation is stated below:

Answer:

214

Step-by-step explanation:

Given that :

Probability of picking a red out of a bag of colored marble = 3 : 7 ; that is 3 / 7

P(red) = 3 / 7

If the number of picks (with replacement) = 500

Then, the approximate number of red marbles chosen will be :

P(red) * number of picks

3/7 * 500 = 214.285

Approximate Number of red marbles chosen = 214
