Answer:
Which of the following sampling techniques is the most likely to produce a random sample, representative sample of all students at a high school?
A. Choosing every 10th name on the student roster
B. Choosing every 10th student arriving in a 9th grade homeroom
<u>C. Choosing the first 100 students who arrive at school
</u>
D. Asking students to call a phone number to answer survey questions
Step-by-step explanation:
Okay so I am not 100% sure but I think it is C. 1/12;
Because if you rearrange all the letters so that W is is the beginning you get 6 different combinations.
Then I multiplied those 6 combinations by 4 because there are 4 letters.
Once I multiplied I got 2/24 because there are 24 possibilities in total, and we are looking for the probability of getting those 2 combinations.
I simplified 2/24 to its lowest form and I got 2/24 = 1/12.
So the correct answer is C.1/12, hope this helps!
