We add the total number of people 175 to 180 and the total number of people taller than 180 together. 90 + 74 = 164

We divide this number by the total number of people in the survey.

250 ÷ 164 = 0.656

Therefore the answer is D.

1) There are 90 + 74 people who are "at least 175 cm tall" (164 ppl)
2) probability is 164/250 = 0.656
