LoginThis is because the relationship between alpha and beta is : Beta = [ alpha / (1 - alpha)].
>> 0.9/(1-0.9)
0.9/0.1 =9
As.. Beta = alpha/(1-alpha)
=0.9(1-0.9)
=0.9/0.1
=9
Because beta = alpha/(1-alpha) is the relation and after calculation we get:
beta = 0.9/(1-0.9) = 0.9/0.1 = 9, which is the answer.
