Quizplus · Accepted Answer

To find the probability that a mother with some college smoked during pregnancy, we need to look at the row for "Some college" and the column for "Smoked during pregnancy". The value in the corresponding cell is 164. To find the probability, we divide by the total sample size (which is the sum of all the values in the table). So,

Probability = 164 / 1024 ≈ 0.1601

Therefore, the best choice is C.
