Answer:

27%

Step-by-step explanation:

take the number of times it is at 2 cars (16) and divide by the number of surveyed times in total (60). multiply by 100 to show answer as a percent

Answer 2

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%
