Country

Country A $75598 $1590

Country B $71320 $3470

Country C $73874 $2081

Use appropriate notation!

Question 1

Sketch the curve and label the values of , 1, 2 and 3, for each country (i.e., three graphs are required, one for each country)

What is the probability of selecting a person with a salary of less than or equal to $75000

- From country A?
