Suppose the probability to die if you get the Covid disease is $1\%$ (just an assumption, it's not a real number) and $3\%$ of death are people who have a comorbidity $C$. So using conditional probability:
$P(\text{Death|get covid}) = 1\%$
$P(\text{have a comorbidity|death and get Covid}) = 3\%$
I want to know the $P(\text{death|get Covid, comorbidity C})$, I have an intuition I only need these information to solve this problem, but I couldn't do it using only what I have.
