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 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?

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.
