The probability of selecting someone who commutes by bus is 20% or 0.2. The probability of selecting someone who does not commute by bus is 1 - 0.2 = 0.8. The odds against selecting someone who commutes by bus are the ratio of the probability of not commuting by bus to the probability of commuting by bus, which is 0.8:0.2 or 4:1.
