The expected time $$\left( {{t_e}} \right)$$ of a $$PERT$$ activity in terms of optimistic time $$\left( {{t_0}} \right)$$, pessimistic $$\left( {{t_p}} \right)$$ and most likely time $$\left( {{t_L}} \right)$$ is given by

$${t_e} = {{{t_0} + 4{t_L} + {t_P}} \over 6}$$

$${t_e} = {{{t_0} + 4{t_P} + {t_L}} \over 6}$$

$${t_e} = {{{t_0} + 4{t_L} + {t_P}} \over 3}$$

$${t_e} = {{{t_0} + 4{t_P} + {t_L}} \over 3}$$
