You are a store manager of an electronics store. You are interested in finding out the probabilities that a customer who bought a computer will also buy an extended warranty plan, computer installation service, or both. You looked at your records and found out that out of 199 customers, 71 buy a warranty and 14 buy both a warranty and installation.
What is the probability that a customer will buy the installation, given that the customer already bought a warranty? Round your answer to two decimal places.
