There are 11 pens in a box : 5 pens are red , 4 pens are blue and 2 pens are green. One pen is selected at random from the box. What is the probability that pen is green?

18.2%

Step-by-step explanation:

Using the color of the pen/the total pen amount you can get 18.1818181818181818... which rounded up to the tenth is 18.2%

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

it has the same slope and a different y-intercept

hope this : )
