60 people are randomly asked what their favorite grocery store is. 40% stated it was Publix,
10% stated SweetBay, ¼ stated Walmart. If the rest chose local markets, what is the
probability of that a randomly chosen person out of the 60 would have chosen a local
market?
First, we find the number of people who chose each of the given stores:
40% of 60 people chose Publix: (0.4) * (60) = 24 people
10% of 60 people chose SweetBay: (0.1) * (60) = 6 people
1/4 of 60 people chose Walmart: (1/4) * (60) = 15 people
Next, we find the total number of people who chose Publix, SweetBay, and Walmart:
24 people (Publix) + 6 people (SweetBay) + 15 people (Walmart) = 45 people
Now, we find the number of people who chose local markets:
60 people (total) - 45 people (other stores) = 15 people
Finally, we calculate the probability that a randomly chosen person out of the 60 would have chosen a local market:
15 people (local market) / 60 people (total) = 1/4 or 25% probability.
