Webb• Probability theory provides the mathematical rules for assigning probabilities to outcomes of random experiments, e.g., coin flips, packet arrivals, noise voltage • Basic elements of probability: Sample space: The set of all possible “elementary” or “finest grain” outcomes of the random experiment (also called sample points) WebbExample 1: Joseph and David are playing with cards and in a pack, there are 52 cards. Joseph drew a card at random with a replacement. Then he asked David what is the …

Webb7 dec. 2024 · An example of independent events is the probability of getting heads on two coin tosses. The probability of getting a head on the first coin toss does not have an impact on the probability of getting heads on the second coin toss. Visual Representation.
