A car wash has three different types of washes: basic,
classic, and ultimate. Based on records, 45% of
customers get the basic wash, 35% get the classic
wash, and 20% get the ultimate wash. Some
customers also vacuum out their cars after the wash.
The car wash records show that 10% of customers
who get the basic wash, 25% of customers who get
the classic wash, and 60% of customers who get the
ultimate wash also vacuum their cars. The probabilities
are displayed in the tree diagram.
What is the probability that a randomly selected
customer purchases the classic car wash if they do not
vacuum their car?
