At a particular garage, 60% of the customers require an oil change, 20% require tire rotation, and 75% of customers require at l

ZanzabumX [31]

Answer:

a. 5%

b. 55%

c. 70%

Step-by-step explanation:

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

$P(O)+P(T)+P(O\&T) = 0.75\\P(O)+P(O\&T) =0.60\\P(T)+P(O\&T) = 0.20\\P(O)+P(T)+P(O\&T) -[P(O)+P(T)+2P(O\&T)]=0.75 -(0.60-0.20)\\P(O\&T)=0.05=5\%$

The probability is 5%

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

$P(O)+P(O\&T) = 0.60\\P(O\&T) = 0.05\\P(O) =0.60-0.05 = 0.55 = 55\%$

The probability is 55%

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

$P(O)+P(T)+P(O\&T) = 0.75\\P(O\&T) = 0.05\\P(O)+P(T) =0.75-0.05 = 0.70 = 70\%$

The probability is 70%
