Question

Which of the following scenarios is most likely to give the best approximation of the true probability of the event specified?

A. find 10 adults and ask them how many drink coffee

B. ask the students seated to your left and right if they watched a certain television program last night

C. sample 3 friends and ask them how many are members of the Republican party

D. determine the ethnicity of 100 men in a sample from a large city and determine the number who are Caucasia

Answer 1

The most accurate and most likely probability is found by having a large, non-biased sample. The answer choice that shows this is D. Determine the ethnicity of 100 men (assumingly selected randomly) from a large city and determine the number who are Caucasian.

This answer choice showcases a large sample group, that was selected randomly from a large city. This would give you varied people to contribute to your study and give you an accurate representation of what the demographics of the city are.

I hope this helps! :)
