Question College degrees awarded in the U.S

Ok my name is Ben am having trouble with a Statistics homework assignment. I have made 2 attempts at the problem and have gotten 1.25 points out of the 2.25 total. I would like some input on how I can figure out what the second part of the question is asking me.

I am unsure how to calculate the percentage of all men who earn bachelor degrees. It is quite frustrating

it does help if you make a drawing or at least a table.

Below is the joint probability table filled out with what we are immediately told.
Bachelor's degress are 50%. Women get 29% of bachelor's degrees.

$\begin{array}{rrrr}
&\text{Men} &\text{Women} & \\
\text{Bachelor} & &0.29 &0.5 \\
\text{Other} & & &0.5 \\
& &0.59 &1
\end{array}$

We can fill the table out by simply ensuring rows and columns sum up properly

$\begin{array}{rrrr}
&\text{Men} &\text{Women} & \\
\text{Bachelor} &0.21 &0.29 &0.5 \\
\text{Other} & &0.3 &0.5 \\
& &0.59 &1
\end{array}$

$\begin{array}{rrrr}
&\text{Men} &\text{Women} & \\
\text{Bachelor} &0.21 &0.29 &0.5 \\
\text{Other} &0.2 &0.3 &0.5 \\
&0.41 &0.59 &1
\end{array}$

And we see that 21% of all degrees are bachelor's degrees earned by men.
