##### Q71. The expected time (tE) of a PERT activity in terms of optimistic time (tO), pessimistic time (tP) and most likely time (tL) is given by

$\text { (a) } t_{E}=\frac{t_{O}+t_{L}+t_{p}}{3}$

$\text { (b) } t_{E}=\frac{4 t_{O}+t_{L}+t_{p}}{3}$

$\text { (c) } t_{E}=\frac{t_{O}+4 t_{L}+t_{p}}{6}$

$\text { (d) } t_{E}=\frac{t_{O}+4 t_{L}+t_{p}}{3} \text { . }$

Ans: $\text { (c) } t_{E}=\frac{t_{O}+4 t_{L}+t_{p}}{6}$
