You can put this solution on YOUR website! if you set up a table, you would get something like the following. 
 
 
                       type A         type B        total
         men             78             42            120
         women           19             11             30
         total           97             53            150
 if you look at this table,  you will see that there are 11 women with type B  personality out of a total of 150 CEO's.
 
 the probability that, if you pick a CEO at random, you will get a woman with type B personality is therefore 11 / 150.
