ANSWER AS SOON AS YOU SEE THIS PLEASE!!!!

Barbara draws pens randomly from a box containing 5 pens of the same shape and size. There is 1 green pen, 3 red pens, and 1 blue pen. She draws 1 red pen and then another red pen without replacing the first one. Find the probability of drawing 1 red pen followed by another red pen, and show the equation used.

Answer 1

Answer: 1/3

Explanation:

There are three kinds of pens. (P) pen(s)

(G) green: 1p

(R) red: 3p

(B) blue: 1p

But, two of the three red pens were removed leaving

(R) = 1p.

So, the probability of picking a red pen 1/3.

Sorry if I'm wrong/correct me if I'm wrong

Answer 2

She already got rid of two red pens, so there's one red pen left.

Explanation:

5-1=4-1=3. 1 red 1 blue 1 green. 100/3=33.3333333… so her chance of getting another red pen is 33.3333333333333333333333% and a 66.66666666666666666666% chance of not.
