Question

5. A group of people were asked if they believed in space creatures. 182 responded "Yes" and 220 responded No" Find the probability that if a person is chosen at randomthe person does not believe in space creatures.

Answer 1

Answer:

$\frac{110}{201}, 0.55, 55$%

Explanation:

So first you have to find the total number of people.

$182 + 220 = 402$

Then we put that number in a fraction with the number of people who do not believe in the creatures.

$\frac{220}{402}$$55$

Then we simplify it.

$\frac{220}{402}=\frac{110}{201}$

That is our fraction answer. In order to change it into a percent we divide the numerator by the denominator.

$\frac{110}{201}=0.54726368159$

Then we round to the nearest hundredth (or what ever it says).

$0.55$

And that is our decimal. Now to change that into a percent we multiply by 100, or move the decimal to spaces to the right.

55%

And that is our percent.
