The probability that a car that comes into the garage needs both an oil change and a tire rotation is $\frac{12}{35}$ .

Step-by-step explanation:

The conditional probability of an event B given that another event A has already occurred is:

$P(B|A)=\frac{P(A\cap B)}{P(A)}$

Denote the events as follows:

X = cars brought in for service need an oil change

Y = cars brought in for service need a tire rotation

The information provided is:

$P(X)=\frac{3}{5}$

$P(Y|X)=\frac{4}{7}$

Compute the value of P (X ∩ Y) as follows:

$P(Y|X)=\frac{P(X\cap Y)}{P(X)}$

$\frac{4}{7}=\frac{P(X\cap Y)}{3/5}$

$P(X\cap Y)=\frac{4}{7}\times \frac{3}{5}$

$=\frac{12}{35}$

Thus, the probability that a car that comes into the garage needs both an oil change and a tire rotation is $\frac{12}{35}$ .
