Question

A restaurant owner has found that 80% of her customers return to the restaurant within two weeks. She wants to create a tool that will simulate the habits of her customers and allow her to predict the probability that three of the next four customers to visit her restaurant will return within two weeks. Which spinner simulation uses an appropriate device and has the correct number of trials?

Answer 1

Answer: B) a spinner divided into 5 congruent sectors, spun 4 times

Answer 2

You need to create a spinner which accurately represents the habits of her customers and allower her to predict what the probability would be that 3/4 customers to visit will return within two weeks. She knows that 80% of her customers return.
Keeping all that in mind mate, you can see that she'll need a spinner divided into five equal spaces and she'll need to spin it 4 times to get an accurate representation. Hope this helped!
