To find the probability of something happening orsomething else happening, you add together the probability of each happening, and then subtract the probability of both happening.
For instance, the probability of rolling greater than 4 on a dice is 1/3. You could roll 5 or 6. The probability of rolling an even number is 1/2. You could roll 2, 4 or 6. The probability of rolling greater than 4 or an even number is 1/3 + 1/2 - 1/6 which = 2/3

What is another name for Experimental Probability?
Another name for experimental probability is empirical probability. This is the ratio of the number of outcomes in which a specified event occurs to the total number of trials.
How do you find probability?
To find probability in a question you first have to determine the whole number which from the question which will be the denominator next determine the numerator from the question then put that number in the fraction.To find probability u have to look at the possibilities which will be the denominator the find the successes which will be the numerator
Do you divide to find the probability?
Yes, you divide the number of expected outcomes by the number of possible outcomes in order to determine probability.
What is the probability of getting a number greater then 5 on a spinner?
The probability is(the total number of numbers on the spinner minus 5)/(the total number of numbers on the spinner)Another way to express the same probability is1 - 5/(the total number of numbers on the spinner)
How can you find the probability of a simple event if the total number equally likely outcomes is 20?
Each outcome has a probability of 0.05
