Unit 4 – Probability, Random Variables, and Probability Distributions Notes 3 – Discrete and Continuous Random Variables Example: Suppose we toss a coin 3 times. The sample space for this chance process is: Total Number of Outcomes: Probability of any one outcome: Let X = Number of Heads out of 3 coin tosses Symbols Meaning Probability X = 0 X = 1 X = 2 X = 3 Probability Distribution - The probability our random variable takes the value X 1 2 3 P(X)
