Marina bought a bag of 10 chocolate cookies, 35 vanilla cookies, and 30 peanut butter cookies.

If she selects a cookie from the bag without looking, what is the probability she selects a peanut butter cookie?

Respuesta :

Answer:

[tex]\frac{2}{5}[/tex]

Step-by-step explanation:

1) Add all the values.

= 10 + 35 + 30

= 75

2) 75 will be the denominator and the one required will be the numerator.

Since there are 30 peanut butter cookies, the probability is [tex]\frac{30}{75}[/tex].
3) Simplify the fraction if necessary.

Divide both sides by 15.

= [tex]\frac{2}{5}[/tex]
