So the probability of getting Red and King is. P(R ∩ K) = P(R)*P(K/R), We find a new term, P(K/R), called conditional probability. We will describe it in the next part. It is called the Probability of K given R. That means we want to calculate the probability of K, which depends on the previous event. So, P(R ∩ K) = 1/52 * 1/51
