Question 965671
There are 25 students names in a hat. You choose 5 names. Three are boys names
and two are girls. How many of the 25 names would you expect to be boys names?
<pre>
Here is how we think it out:

3 names OUT OF the 5 names are boy's names.

"OUT OF" means "OVER".  <--IMPORTANT!  REMEMBER IT!

3 OUT OF 5 means the fraction 3 OVER 5 or {{{3/5}}}.

So we would expect {{{3/5}}}ths of the 25 names to be boy's names.

{{{3/5}}}ths of 25 is {{{3/5}}}{{{"×"}}}{{{25}}}{{{""=""}}}15 students.

So we would expect 15 of the names to be boy's names.
