Amanda has three different colored pens in her book bag: blue, green and purple. The probability of randomly choosing a blue pen from Amanda’s book bag is 40%. The probability of randomly choosing a green pen from Amanda’s book bag is 10%. Suppose Amanda has 20 pens total in her book bag. How many blue pens would Amanda expect to see in her bag?

If there are 20 pens in total, and the probability of choosing a blue pen is 40%, then there are 0.4 times 20, or 8 blue pens in Amanda's bag.

Let me know if this helps!

1.3

step-by-step explanation:

3x2=6   9x+6

12= 9x

divide by 9

12/9 =

1.3 =x

first one because it can't have a fraction in it
