Probability question using table

There's a question on probability I can't seem to figure out.

There's a table that goes like this

Firm has CROFirm has no CRO
Firm Defaults in 3 years%%
Firm Not Default in 3 years%%

The probabilities on in the table do not add up to 100%.

The question also said the probability of having a CRO overall was 25%.

The question asks what would the Probability that a firm has a CRO given that it has defaulted? Basically P(C|D)

How would one solve this? The numbers don't really matter but Im trying to see the concept on how one would solve this

If I use bayes, how do I get the Probability of Default / P(D) overall?
