Given:
10 blue marbles ; 15 yellow marbles, 5 green marbles, 6 red marbles
A total of 36 marbles.
Probabilities:
1st marble: red = 6/36
2nd marble: yellow = 15/35
6/36 * 15/35 = 6*15 / 36*35 = 90/1260 = 1/14
The probability that Kendra will draw a red marble and then a yellow marble is 1/14.
That is around 13 or 14 cents. The specific answer is 13.65853659 cents, but you can either round up to 14 or round down to 13 (rounding up to 14 is the correct way to do it.)
First you divide 1.12 by 8.2 to get the unit rate because It takes $1.12 to buy 8.2 ounces. 1.12/8.2=13.65853659
