Well, honey, if you're reaching into that bag three times and each time you're pulling out a yellow marble and then putting it back in, the probability of picking a yellow marble each time is 8/21. Multiply that by itself three times because you're picking three marbles, and you get a probability of 512/9261. So, good luck with those yellow marbles, darlin'!

What is the probability of chossing 12 marbles from a jar in numercial order?
The probability of picking the #1 marble on the first draw is 1/12. If you've done that, then the probability of picking the #2 marble on the second draw is 1/11. If you've done that, then, the probability of picking the #3 marble on the third draw is 1/10. If you've done that, then, the probability of picking the #4 marble on the fourth draw is 1/11. etc. etc. So the probability of doing all of them in sequence is (1/12) x (1/11) x . . . x (1/1). That's exactly the reciprocal of (12!). According to my $1.49 calculator, your chances of success without peeking amount to about 0.00000020877 percent (rounded) Not a smart bet.

A bag contains 5 green marbles 3 yellow and 2 red marbles. What is the probability of picking three green marbles from the bag without replacement?
To find the answer to probability, first add all the things together (5+3+2=10), then, find the number of things you will be taking from the group of things (3), and put together as a fraction (3/10). So the final answer is 3/10, which is unlikely. :D
