A certain activity is given optimistic (tO), pessimistic (tP) & likely time (tL) estimates. Assuming the $\beta$ distribution for these time, the expected time (tE) for completing this activity is expressed as
1
tE = (tO + 4 tL + tP)/6
2
tE = (tO - 4 tL + tP)/6
3
tE = (tO + 6 tL + tP)/4
4
tE = (tO - 6 tL + tP)/4
