What is the relationship between probability and sets?
Probability theory often uses set theory to define events. An event is a subset of a sample space.
Can you give me an example of an event as a subset?
Sure! If you have a sample space of rolling a die, the event of rolling an even number is the set {2, 4, 6}.
How do you calculate the probability of that event?
To calculate the probability, divide the number of favorable outcomes by the total outcomes. Here, it's 3/6 or 1/2.
What if I want to find the probability of rolling a number greater than 4?
The event for rolling a number greater than 4 is {5, 6}, so the probability is 2/6 or 1/3.
