Question 1054178
if you set up a table, you would get something like the following.


<pre>


                       type A         type B        total


         men             78             42            120
         women           19             11             30

         total           97             53            150


</pre>


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.
