The variance for this activity is mathematically given as
Var=0.026
A data set's variance may be seen as a measurement of the spread that exists between the individual integers. When evaluating the asset allocation of a portfolio, investors employ an expression known as the variance equation.
After careful consideration of the table given in the question, we have that
Pessimistic time tp=2
optimistic time to=1
most likely time tm=1.5
Generally, the equation for variance is mathematically given as
[tex]\sigma^2=\frac{tp-to}{6}^2[/tex]
Therefore
[tex]\frac{2-1}{6}^2\\\\\sigma^2=1/6^2[/tex]
Var=0.026
In conclusion, the variance for this activity
Var=0.026
