Question

When a researcher asked 35 people if they liked a new brand of toilet paper; 22 said 'yes', 8 said 'no' and 5 were 'undecided'. if a person is ramdomly selected from this group of people, what is the probability that you select a person who said 'undesided'. give your answer as a decimal rounded to the ten-thousandsth place?

Answer 1

To find the probability that someone that is undecided is selected, we can use a method to find probability. That is, probability = choices/total outcomes. Here, since there are 5 people that are undecided, and 35 people in total, then the probability is 5/35 or 1/7.

Now, we need to find what 1/7 is as a decimal. We can do this by dividing 1 by 7. Doing this, we get 0.14285714285... Now we need to round to the ten-thousandths place. The number currently in the ten-thousandths place is 8. Since the number behind 8 is 5, we round up. So, that means that the answer is 0.1429

Answer 2

I guess maybe 5/35 because there are only 5 chances that you could get one of the 5 in the 35 people
