Answer:
(a) Work/leisure choice
(b) Marketing strategy
Explanation:
Microeconomic issues relate to those that are within the scope and power of individuals, households and firms which means that problems here will relate to decisions that these participants make in relation to resource allocation.
Choices relating to leisure or work have to do with the individual and the resources they would need or derive from either work or leisure and so are a microeconomic problem.
The marketing strategy that a firm should pursue is related to an individual firm and so is a microeconomic problem as well.
Answer:
the Expected rate of return will be 8.2%
the variance will be 0.001296
Explanation:
We will calculate the Expected Rate of Return which is the sum of the wieghted return based on their probabilities:
return of 0.15 probability 20% = 0.03
return of 0.07 probability 70% = 0.049
return of 0.03 probability 10% = 0.003
expected return = 0.082 = 8.2%
Now to calculate the variance we do:
∑(rk-ERR)^2 x pk
The sum of the difference between the expected rate and the escenario rate, power two, and multiply by their posibility

the variance will be: 0.001296
