The table contains data about \(47+13+36+4=100\) members in total. We note that 14 of the 100 members in the table are female and Democrats.
The probability is the number of favorable outcomes divided by the number of possible outcomes:
P(Female and Democrats)=# of favorable outcomes/# of possible outcomes \(=13/100=0.13\)
