Respuesta :

We will proceed as follows:

First, we separate the number of professors that are younger than 36:

[tex]\begin{cases}a<36\colon34,33 \\ \\ a\ge36\colon41,75,55,49,67,55,43,53\end{cases}[/tex]

So, there are two professoprs that are younger than 36 among all 10 professors. So the percentage is the following:

[tex]x=\frac{2\cdot10}{100}\Rightarrow x=20[/tex]

So, there is a 20% that is younger than 36 years old.
