Seamus Hardy · Answer 1

the probability that the selected employee works in department A and is not classified as junior level is;

P (A∩J') = 10% or 0.1

Step-by-step explanation:

Given;

Percent of junior level employees J = 40%

Percent of department A employees A = 32%

Percent of junior level employees in department A A∩J = 55% of J

We need to derive the percentage of the employees that are junior level and is in department A;

A∩J = 55% of J = 55% of 40% = 0.55 * 40% = 22%

A∩J = 22%

The percentage of the employees that are in department A but not junior level is;

A∩J' = A - A∩J = 32% - 22% = 10%

Therefore, the probability that the selected employee works in department A and is not classified as junior level is;

P (A∩J') = 10% or 0.1
