A) infinite
B) 1
C) 2
D) 0.5
E) zero
Correct Answer: B
Solution :
The relation between\[\alpha \]and\[\beta \]is \[\beta =\frac{\alpha }{1-\alpha }\] Putting this value in the given equation, we have \[\frac{\beta -\alpha }{\alpha \beta }=\frac{\frac{\alpha }{1-\alpha }-\alpha }{\alpha .\frac{\alpha }{1-\alpha }}=\frac{{{\alpha }^{2}}}{{{\alpha }^{2}}}=1\]You need to login to perform this action.
