What does a probability of 1 indicate?
✔✔A probability of 1 means the event is certain to occur.
What is the intersection of events, and how is it different from the union?
✔✔The intersection of events is the set of outcomes where all events happen, while the union is
the set of outcomes where at least one event occurs.
What is a tree diagram in probability?
✔✔A tree diagram is a visual representation of possible outcomes of an event sequence, showing
paths and their probabilities.
What is the probability of drawing an ace from a standard deck of cards?
✔✔The probability is 4 out of 52, or about 0.077, since there are four aces in a 52-card deck.
Explain why probabilities are always between 0 and 1.

, ✔✔Probabilities represent likelihoods, so they range from 0 (impossible) to 1 (certain), covering
all possible chances of occurrence.
What does it mean to have an outcome space in probability?
✔✔The outcome space, or sample space, is the collection of all possible results for an
experiment, used to calculate probabilities.
How can conditional probability change based on new information?
✔✔Conditional probability is updated based on new information, which can increase or decrease
the likelihood of the event occurring.
What is the probability of rolling an even number on a six-sided die?
✔✔The probability is 3 out of 6, or 0.5, since there are three even numbers (2, 4, and 6) on a six-
sided die.
How is probability used to measure uncertainty?
✔✔Probability quantifies uncertainty by assigning a likelihood to different possible outcomes,
helping to predict and make decisions in uncertain situations.
