Finding the Probability of Independent Events
(Sample space UNCHANGED)
If A and B are independent events, then
P(A and B) = P(A)•P(B)
Finding the Probability of Dependent Events
(Sample space DECREASES)
If A and B are dependent events, then
P(A and B) = P(A) • P(B given A)

Probability – Counting Principle Probability – Independent Event Probability Application
Theoretical probability
Theoretical Probability is determined through reasoning (the ratio of the number of favorable outcomes to the number of possible outcomes).
Experimental probability
Experimental probability is found by repeating an experiment and observing the outcomes.
A monkey is sitting by and hitting 4 keys randomly. Suppose that the monkey is answering a multiple choice MATH STAAR TEST. There are 56 questions and each question has 4 options. Find the experimental probability
