From given information 1.7 % from A , 3.68 % from B and 2% from C need tuning. So total 7.38 % , therefore
(i) Probability = 0.00738 and
(ii) Probability = 0.00368
A hotel gets cars for its guests from three rental agencies, 34% agency A, 46% agency B,20% agency C.If 5% of the cars from A, 8% of the cars from B, and 10% of the cars from C need tune-ups, find probability
i) a car needing a tune-up will be delivered to one of the guess.
ii) if a car needing a tune up is delivered to one of the guests, it came from agency B.
who can help me solve this question. thanks ><

A = Car from garage A
B = Car from garage B
C = Car from garage C
T = Car Needs tune up
i) a car needing a tune-up will be delivered to one of the guests.
(note only 1 zero after the decimal)
ii) if a car needing a tune up is delivered to one of the guests, it came from agency B.
use the formula for conditional probability
