What is the probability that Bobby’s mother has a brown car? Explain your answer.
Her car has no chance of being brown. According to Bobby’s results, there were no brown cars.

What is the probability that Bobby’s mother does not have a black car? Explain your answer.
There is a 4/5 chance that she does not have a black car. If I add up all the cars that are not black, I get 36. This means that there is a 36 to 45 probability that her car is not black. 36/45 is 4/5 in lowest terms because 9 goes into 36 4 times and
9 goes into 45 5 times.

What is the probability that Bobby’s neighbor across the street has a red or blue car? Explain your answer.
There is a 16/45 chance that the car is red or blue. If you add the red and blue cars together, you get 16. This means that 16 out of the 45 cars are red or blue.
