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.

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.
