Question

the probability of pulling a red marble out of bag of colored marbles is 3:7.if you were to pull color marbles out of the bag (one at a time,and putting the the marble back each time)Ford Five Hundred tribes approximately how many times would you select a red marble

Answer 1

Question isn't well formatted ;

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

Answer:

214

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
