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?

Respuesta :

Answer:

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!
