We are interested in the probability of the event E = A ∪ B, namely drawing a King or a heart. The odds of drawing a King or a heart are P(E)/P(E') = (4/13)/(9/13) = 4/9. What is the probability of getting at least one black card in a 7-card hand off a shuffled 52-card deck.
QUESTIONS ; WHAT IS THE PROBABILITY OF DRAWING A KING OR A HEART FROM A DECK OF CARD?
ANSWER ; IN MY OPINION WE ARE INTERESTED IN THE PROBABILITY OF THE EVENT E = A U B, NAMELY DRAWING A KING OR A HEART. THE ODDS OF DRAWING A KING OR A HEART ARE P(E)/(P(E') = (4/13)/(9/13) = 1/9. / || The number of kings in a deck are 4
Number of hearts in the deck are 13, including the king of hearts
Probability of getting either a king or a heart is, P = 4+(13–1) / 52
