If you have 8 marbles (5 green and 3 blue), what is the probability of drawing a green, then 2 blues, and then a green without any
replacement?
a. 0%
b. 2%
c. 7%
d. 11%

C. 7%

Explanation:

Hahah I used to really struggle with probability, but once you get it, the concept is super easy to apply to everything else!

The total amount of marbles is 8.

On the first draw, the probability of drawing a green is 5/8.

On the second draw, the probability of drawing a blue is 3/7.

  Remember that you took a green out, and never put it back

On the third draw, the probability of getting blue is 2/6.

  Remember you've taken 2 marbles out, and one of them has been blue.

On the fourth day, the chance of getting green is 4/5.

You multiple all of these together to get:

1/14, or 0.0714, or ~7%

Good luck!
