Based upon the results given, the probability of selecting a black car is 25/220. Therefore, multiplying by 216 (the number of cars selected for a test drive) gives us:
25/220 * 216 ≈ 24.545
Therefore, we would expect approximately 25 black cars to be selected for a test drive out of 216.
So the closest answer choice is: 20 cars should be black.
12.
red 70 green 22 silver 85 blue 10 black 25 white 58
Based upon these results, if a car is randomly selected for a test drive 216 times, how many of the cars should be black?
18 cars should be black
8 cars should be black
20 cars should be black
46 cars should be black
