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\%](https://tex.z-dn.net/?f=P%28O%29%2BP%28T%29%2BP%28O%5C%26T%29%20%3D%200.75%5C%5CP%28O%29%2BP%28O%5C%26T%29%20%3D0.60%5C%5CP%28T%29%2BP%28O%5C%26T%29%20%3D%200.20%5C%5CP%28O%29%2BP%28T%29%2BP%28O%5C%26T%29%20-%5BP%28O%29%2BP%28T%29%2B2P%28O%5C%26T%29%5D%3D0.75%20-%280.60-0.20%29%5C%5CP%28O%5C%26T%29%3D0.05%3D5%5C%25)
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\%](https://tex.z-dn.net/?f=P%28O%29%2BP%28O%5C%26T%29%20%3D%200.60%5C%5CP%28O%5C%26T%29%20%3D%200.05%5C%5CP%28O%29%20%3D0.60-0.05%20%3D%200.55%20%3D%2055%5C%25)
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\%](https://tex.z-dn.net/?f=P%28O%29%2BP%28T%29%2BP%28O%5C%26T%29%20%3D%200.75%5C%5CP%28O%5C%26T%29%20%3D%200.05%5C%5CP%28O%29%2BP%28T%29%20%3D0.75-0.05%20%3D%200.70%20%3D%2070%5C%25)
The probability is 70%

<h2>30% of 8 cups is 2.4 cups</h2>
Step-by-step explanation:
![\bold{METHOD\ 1:}\\\\p\%=\dfrac{p}{100}\\\\30\%=\dfrac{30}{100}=0.3\\\\30\%\ of\ 8\ cups\to0.3\cdot8\ cups=2.4\ cups](https://tex.z-dn.net/?f=%5Cbold%7BMETHOD%5C%201%3A%7D%5C%5C%5C%5Cp%5C%25%3D%5Cdfrac%7Bp%7D%7B100%7D%5C%5C%5C%5C30%5C%25%3D%5Cdfrac%7B30%7D%7B100%7D%3D0.3%5C%5C%5C%5C30%5C%25%5C%20of%5C%208%5C%20cups%5Cto0.3%5Ccdot8%5C%20cups%3D2.4%5C%20cups)

75% becuase it is more than 5o% by the looks of it
