The odds of an event happening is defined as the probability of the event occurring divided by the probability of the event not occurring. Therefore, the odds of a student not owning a tablet computer is: 
(Probability of not owning a tablet) / (Probability of owning a tablet) = 0.20/0.80 = 0.25 or 1:4. Therefore, the correct answer is B, which represents the odds of not owning a tablet as 0.25.
