In games of chance, understanding complementary events is important for making good predictions.
Complementary events are pairs of outcomes where one must happen if the other does not.
For example, when you flip a coin, the two complementary events are "heads" and "tails."
This means if we know the chance of one event happening, we can easily find the chance of the opposite happening.
For instance, if the chance of rolling a 3 on a fair six-sided die is ( P(3) = \frac{1}{6} ), then the chance of not rolling a 3 is:
[ P(3') = 1 - P(3) = 1 - \frac{1}{6} = \frac{5}{6} ]
Knowing the probabilities of both an event and its complement helps us make smart predictions.
In a game with several rounds, if an event has a chance of (0.4) (or 40%) of happening, then its complement has a chance of (0.6) (or 60%). This shows that different outcomes are more likely in the next rounds.
Using complementary events when calculating probabilities helps players make better strategies and improve their chances in games of chance.
