You can put this solution on YOUR website! Four candidates are seeking a vacancy on a school board . If A is twice as likely to be elected a B, and B and C are given about the same chance of being elected , while C is twice as likely to be elected as D , what are the probability that :
-------
D = D
C = 2D
B = 2D
A = 4D
----
D + 2D + 2D + 4D = 1
9D = 1
------------
D = 1/9
C = 2/9
B = 2/9
A = 4/9
a) C will win:::: 2/9
b) A will not win:::: 5/9
