(a) If you roll a fair 6-sided die, what are the odds for rolling a 5 or higher?
(b) If you roll two fair 6-sided dice, what are the odds against rolling a sum of 7?
(c) If you draw a card at random from a standard deck, what are the odds for drawing a $♡$?
(d) If you draw 2 cards at random from a standard deck, what are the odds against them both being $♠$?
