Question 59094
Hi Gerald,
Way to butter us up with the whole "math expert" thing!
:
Below are the results of a survey:
:
Major
Male -  Female
Accounting  100 (M) -   100 (F)
Management  150 (M) -   50(F)
Finance     50   (M)-  50(F)
Total       300  (M)-  200(F)

A) What is the probability of selecting a female student?  
The total number of Females over the total numeber of students is:
P=200/(200+300)=200/500=2/5 
:
B) What is the probability of selecting a finance or accounting major?
Total Number of finance students over total number of students + total number of accounting majors over the total number of students is: 
P=(100+100)/500+(150+50)/500=200/500+200/500=400/500=4/5
:
C) What is the probability of selecting an accounting major, given that the person selected is a male?
The total number of accounting majors that are male over the total number of males is:
p=100/300=1/3

Happy Calculating, Gerald!!!
