so the table represents the the persons employed with an advanced degree and the persons not employed with an advanced degree
OpenStudy (anonymous):

OpenStudy (anonymous):
we add the people that are employed and and not employed with an advanced degree and multiply it the people that are employed

(ignore the first part, thought it was a dependent situation again it's easier than that)
OpenStudy (anonymous):

OpenStudy (fibonaccichick666):

OpenStudy (anonymous):

ok so i have to add up all the people who are employed?
OpenStudy (fibonaccichick666):
no you have the answer i think
OpenStudy (fibonaccichick666):
yup yup jt
OpenStudy (anonymous):
ok so .72?
OpenStudy (fibonaccichick666):
because it is not conditional for the advanced degree, it's considered given in my mind at least
