There is a 1/3 chance that a red marble would be chosen.

To find out you put add up the marbles, so they will make 12 marbles.

Since there are 4 red you put 4/12.

4/12 simplified is 1/3.

So the chance of a red marble being picked is 1/3.

Nikki has 3 pieces of yarn. the first piece is 5/6 feet long the second piece is 5/3 feet long and the third piece is 3/2 oder s

I think you are asking to sort them according to the shortest to longest in length. For this, it would be helpful to write the fraction into decimal. The equivalent values are as follows:

5/6 = 0.83
5/3 = 1.67
3/2 = 1.50

Therefore, the correct sorting would be as follows:

first yarn
third yarn
second yarn

Hope this answers the question. Have a nice day.
