Question 710392
Find the probability of event A given that: 
(a) the odds in favor of A are 3:2
Note: odds for = P(A)/P(not A)
Equation:
P(A)/P(not A) = 3/2
2P(A) - 3P(not A) = 0
----
2P(A) - 3(1 - P(A)) = 0
2P(A) -3 + 3P(A) = 0
5P(A) = 3
P(A) = 3/5
==================
 
(b) the odds against A are 4:1
P(A) = 1/5
===============
