A bag contains 20 identical-looking balls: 8 red, 5 blue, 4 green, and 3 yellow. Separately, a standard deck of 52 playing cards, with no jokers, is shuffled thoroughly before each draw. For every question below, unless it says otherwise, exactly one ball is drawn at random from the bag, or exactly one card is drawn at random from the deck, and each question should be treated independently of every other question, as if the bag and deck were freshly reset each time.

The deck contains the usual four suits -- spades, hearts, diamonds, and clubs -- of thirteen cards each, including one ace, nine numbered cards, and three face cards (jack, queen, and king) per suit. Spades and clubs are the black suits, while hearts and diamonds are the red suits.
