Practice question · Select all that apply
One card is drawn from a standard 52-card deck. Select every statement that is true.
Hints
- Count the favourable cards in each case out of 52.
- Ask whether any single card is both a heart and a king.
Show the answer
- A. P(heart) = 1/4
- D. P(not a heart) = 3/4
- E. P(king) = 1/13
Why
13/52 = 1/4 and 4/52 = 1/13 are right, and the complement of a heart is 3/4. But the king of hearts is one card in both events, so P(heart and king) = 1/52, not 0, and P(heart or king) must subtract that overlap, giving 16/52.
