a) Empirical probability because the probability results from an estimate

b) Classical probability because each outcome in the sample space is equally likely

c) Subjective probability because the probability results from an estimete

d) Classical probability because the probability is based on observations obtained from a probability experiment

e) Subjective probability because each outcome in the sample space is equally likely

With $P(A)=\frac{1}{13},\text{}P(H)=\frac{1}{4}$ and $P(R)=\frac{1}{21}$ I get $\frac{1}{4}$ for $P(H|R)$. So this basically says that P(H) and P(R) are independent, since H and P are independent iff $P(H|R)=P(H)$ . I know that that's not correct from the source, so now I am wondering how I can then calculate the conditional probability for dependent events and how I would know beforehand. Why is $P(H|R)$ actually $\frac{1}{2}$ ?
