Question

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.

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. What is the probability that a randomly selected customer will get the classic wash and vacuum their car?

    to find the probability we need to use the conditional probability formula.

    P(A/B)=P(A ? B )/P(B)

    this is the probability that A happens after B has happened.

    In this case we need to defined:

    A=Vacuum

    B=classic wash

    Then: A ? B =

    classic wash and vacuum

    once we defined the events , we have to find their probabilities:

    P(B)=.35

    P(A ? B) =.25

    Therefore:

    the answer is B  

    you need only to multiply 0.35 by 0.25

    and round to hundreths
