A firm offers routine physical examinations as part of a health service program for its employees. The exams showed that 22% of the employees needed corrective shoes, 29% needed major dental work, and 3% needed both corrective shoes and major dental work. What is the probability that an employee selected at random will need either corrective shoes or major dental work

0.48 = 48% probability that an employee selected at random will need either corrective shoes or major dental work

Step-by-step explanation:

I am going to solve this question treating these events as Venn probabilities.

I am going to say that:

Event A: Employee needed corrective shoes.

Event B: Employee needed major dental work.

22% of the employees needed corrective shoes

This means that

29% needed major dental work

This means that

3% needed both corrective shoes and major dental work.

This means that

What is the probability that an employee selected at random will need either corrective shoes or major dental work?

This is:

Replacing the values that we have:

0.48 = 48% probability that an employee selected at random will need either corrective shoes or major dental work

what are the options? ?
