"$\alpha = {{{I_C}} \over {{I_E}}}$, $\beta = {{{I_C}} \over {{I_B}}}$; ${I_E} = {I_C} + {I_B}$

$$\alpha = {{{I_C}} \over {{I_C} + {I_B}}} = {{{I_C}/{I_B}} \over {{{{I_C}} \over {{I_B}}} + 1}} = {\beta \over {\beta + 1}}$$

$1 + {1 \over \beta } = {1 \over \alpha }$

${1 \over \beta } = {{1 - \alpha } \over \alpha }$

$\beta = {\alpha \over {1 - \alpha }}$"

For a transistor $\alpha$ and $\beta$ are given as $\alpha = {{{I_C}} \over {{I_E}}}$ and $\beta = {{{I_C}} \over {{I_B}}}$. Then the correct relation between $\alpha$ and $\beta$ will be :
