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?
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
If the initial height changes, then the term in the equation that represents that height will change. The initial height term is hi, so it changes from 58 to 0.
