Answer:
27%
Step-by-step explanation:
We are given the results of survey of one thousand families to determine the distribution of families by their size.
We are to find the probability (to the near percent) that a line has exactly 2 cars in it.
Frequency of 2 cars in a line = 16
Total frequency = 2 + 9 + 16 + 12 + 8 + 6 + 4 + 2 + 1 = 60
P (2 cars in line) = (16 / 60) × 100 = 26.6% ≈ 27%
