Question 473140
A class is collecting data on eye color and gender. They organize the data they collected into the table below. Numbers in the table represent the number of students from the class that belong to each of the ctegories. Express probabilities as simplifed fractions.  
        brown blue green..Total
Male    22    18   10.....50  
Female  18    20   12.....50
Total...40....38...22....100
----------------------------
 Find the probablity that a randomly selected studen from this class
a. doesnt have brown eyes:: 60/100
------------
b. has brown eyes or blue eyes:: 62/100
------------
c. is female or has green eyes::(50+22-12)/100 = 60/100
---------------
d. is male, given the student has blue eyes::10/22
---------------
e. If two people are randomly,selected, in succession, from the students in this class, find the probablity that they both have green eyes?::
22C2/100C2 = 231/4950 = 0.0467
