∙ 7y agoIt is necessary to have an estimate of the proportion of families in the town which own cars. Since the number of families which do own a car is given, it is necessary to know the total number of families in the town. Without the total number of families, it is not possible to estimate the car-owning proportion and therefore impossible to make any estimate about the answer.
If, for example, if there were only 65 families this would imply that every family owned a car and, therefore, the probability of exactly 5 out of 7 random families owning a car would be 0. If there were 67 families, the probability would be approx 0.17 while if there were 270 or more families, the probability is zero.

∙ 7y agoThe probability that exactly 4 out of 6 randomly selected vehicles will pass the test when the pass rate is 80% is approx 0.2458 (or nearly a quarter).
The answer would depend on the demographics of the population: a probability of 0.2 it too high unless the population is from a retirement area.

They are exactly the same
Exactly 1.
