Probability of people needing corrective shoes or dental work is 0.36.
<h3>
What is probability?</h3>
The proportion of favorable cases to all possible cases used to determine how likely an event is to occur.
<h3>What are mutually exclusive events?</h3>
A statistical term used to describe events that cannot occur concurrently is "mutually exclusive".
Here, the two events getting corrective shoes and getting dental work are not mutually exclusive events.
P(corrective shoes or dental work) = P(corrective shoes) + P(dental work) - P(corrective shoes and dental work)
P(corrective shoes or dental work) = 0.16 + 0.23 - 0.03
P(corrective shoes or dental work) = 0.36
Hence, the probability of people needing corrective shoes or dental work is 0.36.
