Ques: find the area bounded by
|2y-5| = 12 - |3x-5|
The statement:
Area bounded by |2y-5| = 12 - |3x-5| will be equal in area to that bounded by |2y| = 12 - |3x|
how do you arrive at this^
A man buys two boxes of matches, each of which contains matches and puts them in his pocket. Every time he has to light a match, he selects at random one box or the other. What is the probability that there are exactly k (1other box? 
Suppose a diagnostic test for a certain disease is 90% accurate.
In other words the false positive rate and the false negative rate are both 10%.
If 3% of the population has the disease, find the probability that a random person
who tests positive for the disease actually has the disease.
