Calculate the probability of a single event
Question
Calculate the probability of a single event
Solution
To calculate the probability of a single event, you need to know the total number of outcomes and the number of ways the event can occur. The formula for probability is:
P(E) = Number of ways event E can occur / Total number of outcomes
For example, if you are rolling a six-sided die, the total number of outcomes is 6 (because there are 6 possible numbers that can come up). If you want to find the probability of rolling a 3, the number of ways that event can occur is 1 (because there's only one 3 on the die). So the probability of rolling a 3 is 1/6.
