Question

As part of a​ sixth-grade class​ project, the teacher brings to class a large jar containing 200 gumballs of two different​ colors: red and green. Andy is asked to draw a sample of his own choosing and estimate the number of red gumballs in the jar. Andy draws a sample of 4040 ​gumballs, of which 88 are red and 3232 are green. Use​ Andy's sample to estimate the number of red gumballs in the jar.

Answer 1

There would be 40 red gumballs

Explanation:

Since, out of 40 gumballs there are 8 red gumballs,

So, the ratio of red gumballs and total gumballs =
`(8)/(40)`

`=(1)/(5)`

Now, let there are x red gumballs in 200 gumballs,

The ratio of red gumballs and total gumballs =
`(x)/(200)`

`\implies (x)/(200)=(1)/(5)`

`x =(200)/(5)=40`

Hence, the possible number of red gumballs in the jar would be 40.
