Answer:
B. 6.5 days
Step-by-step explanation:
The estimated time for completing an activity can be computed if we have optimistic time, most likely time and pessimistic time
The formula is:
[tex]T_e = \frac{T_0+4T_m+T_p}{6} \\where\\T_0 = Optimistic\ Time\\T_m = Most\ likely\ time\\T_p=Pessimistic\ time[/tex]
For activity B:
[tex]T_0=3\\T_m=6\\T_p=12[/tex]
Putting the values in the formula
[tex]T_e = \frac{3+4(6)+12}{6}\\T_e=\frac{3+24+12}{6}\\T_e=\frac{39}{6}\\T_e=6.5\ days[/tex]
The correct answer is:
B. 6.5 days ..
