Answer 1

The variance for this activity  is  mathematically given as

Var=0.026  

What is the variance for this activity?

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

$\sigma^2=\frac{tp-to}{6}^2$

Therefore

$\frac{2-1}{6}^2\\\\\sigma^2=1/6^2$

Var=0.026  

In conclusion,  the variance for this activity

Var=0.026
