Question

a vending machine dispensed the following snacks: 5 granola bars, 15 chips, and 20 cookies. what is the experimental probability that the next snack dispensed will be cookies? write your answer as a fraction. p(cookies)= _

Explanation:

Step1: Calculate total number of snacks

$5 + 15+20=40$

Step2: Calculate probability of cookies

The number of cookies is 20. Probability formula is $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So $P(\text{cookies})=\frac{20}{40}$

Answer:

$\frac{20}{40}$
