The correct answer is:
$20-100$
$\beta=\frac{\alpha}{1-\alpha}$
$\beta_1=\frac{\frac{20}{21}}{1-\frac{20}{21}}=20, \quad \beta_2=\frac{\frac{100}{101}}{1-\frac{100}{101}}=100$
The value of $\beta$ lies between $20-100$.
$\beta_1=\frac{\frac{20}{21}}{1-\frac{20}{21}}=20, \quad \beta_2=\frac{\frac{100}{101}}{1-\frac{100}{101}}=100$
The value of $\beta$ lies between $20-100$.
