Making concrete, it is important to use the correct concrete mixing ratios to produce a tough, long life, durable concrete mix. This could be expressed as follows: So, in this example, if the probability of the event occurring = 0.80, then the odds are 0.80 / (1-0.80) = 0.80/0.20 = 4 (i.e., 4 to 1). Difference Between Absolute and Relative Absolute vs Relative Absolute came from the Latin words absolute and absolvere which mean “to set free or make separate”.
