In statistics, we can sort events into different types based on what happens. Knowing about these event types is really important for experiments and probability.
A simple event is when you have just one outcome.
For example, if you roll a six-sided die, getting a 3 is a simple event.
The sample space (which means all possible outcomes) in this case is {1, 2, 3, 4, 5, 6}.
A compound event has two or more simple events combined.
For instance, if you flip a coin and roll a die at the same time, that makes a compound event.
The sample space here would include combinations like (Heads, 1), (Heads, 2), (Tails, 5), and so on.
Complementary events are pairs of events that complete each other.
For example, if you pick a red card from a deck, the complementary event would be picking a non-red card.
Together, these outcomes cover everything possible in the sample space.
Independent events do not impact each other.
A good example is rolling a die and flipping a coin at the same time.
Dependent events, on the other hand, do rely on each other.
An example would be drawing two cards from a deck without putting the first card back.
By understanding these event types, we can better analyze experiments and what happens in them!
