Question 1097610
=======Attend=====Not===totals
Meets----45--------20----65
doesn't--15--------20----35
totals---60--------40---100

I used 100 workers, of whom 60 attended and of those 75% met production quota and 25% did not.  That is the first column.  The 2nd column does it with 50%, and the sums add to 100
For 1, the probability of meeting is 0.65
For 2, the worker who meets (65) attended (45) is 45/65=9/13=0.69
