Thank you for the opportunity to help you with your question!

a) Number of cars with exactly one of the repairs done = 28 brake repairs+21 exhaust repairs+ 13 transmission repairs = 28+21+13= 62

b) total number of cars =105

total cars repaired = 28+21+13+8+6+3+1=80

number of cars without any repair =105-80 =25

c) Number of cars with exactly two repairs = 8+6+3 = 17

Please let me know if you need any clarification. I'm always happy to answer your questions.
