You survey customers at a restaurant who have contracts with three different wireless telecommunication providers. The survey asks whether they have cell phone service at the restaurant. The results, given as joint relative frequencies, are shown in the two-way table. Find the probability that a randomly selected customer has a contract with provider B. Then find the probability that a randomly selected customer who does not have cell phone service has a contract with provider B. Write your answers as decimals rounded to the nearest hundredth. Use your answers to determine whether having a contract with provider B and not having cell phone service are independent events.
