The probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
a) 26/52 * (26-1)/(52-1) = ?
b) Either-or probabilities are found by adding the individual probabilities. The probability above for red plus the same probability for black.
c) 4/52 * 4/(52-1) = ?
Use a similar thinking process for d.
Two cards are drawn without replacement from a standard deck of 52 cards. Find the probability a) both cards are red ,b) both cards are the same color, c) the second card is a king given that the first card is a queen, d) the second card is the queen of hearts given that the first card is black
