Alexxandr [17]

Answer: A. 0.20

Step-by-step explanation:

Let A be the event of employees needed corrective shoes and B be the event that they needed major dental work .

We are given that : P(A)=0.08\ ;\ P(B)=0.15\ ;\ P(A\cap B)=0.03

We know that P(A\cup B)=P(A)+P(B)-P(A\cap B)

Then,   P(A\cup B)=0.08+0.15-0.03= 0.20

Hence, the probability that an employee selected at random will need either corrective shoes or major dental work : P(A\cup B)= 0.20

hence, the correct option is (A).
