At a particular garage, 60% of the customers require an oil change, 20% require tire rotation, and 75% of customers require at least one of these services. for a randomly selected customer,

a. what is the probability that the customer will need both services?

b. what is the probability that the customer will need an oil change, but not a tire rotation?

c. what is the probability that the customer will want exactly one of these two services?

a. 5%

b. 55%

c. 70%

Step-by-step explanation:

a. The probability of customer wanting both services (P(O&T)) is:

The probability is 5%

b. The probability that the customer will need an oil change, but not a tire rotation (P(O)) is :

The probability is 55%

c. The probability that the customer will want exactly one of these two services (P(O)+P(T)) is:

The probability is 70%

answer: 590

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
