The probability of an event is often expressed in terms of odds. Specifically, when we say that the odds are k to m that an event will occur, we mean that the probability of the event is k / (k + m). For instance, "the odds are 4 to 1 that candidate Jones will win" means that P(Jones will win) = 4/5 = .8. Express the following statements in terms of probability. (Bookmakers give the odds of not winning.)

(a) The odds are 3 to 1 that there will be good weather tomorrow.
(b) The odds are 8 to 3 that the city council will delay the funding of a new sports arena.
