ISDS Exam 2 Probability - correct answer ✔✔A numeric value that measures the likelihood that an event occurs What can a probability range from? - correct answer ✔✔0 to 1 An impossible event for a probability - correct answer ✔✔If the probability is 0 Union of two events (A U B) - correct answer ✔✔Is the event consisting of all events in both A or B When a probability have a definite event - correct answer ✔✔When a probability is 1 event exhaustive - correct answer ✔✔When two events combined, they include all outcomes in the sample space experiment - correct answer ✔✔A process that leads to one of several possible outcomes sample space - correct answer ✔✔Contains all possible outcomes of the experiment Event - correct answer ✔✔Any subset of outcomes of an experiment Mutually Exclusive - correct answer ✔✔When two events share no outcomes Intersection of two events - correct answer ✔✔Is the event consisting of all events in both A and B complement of event - correct answer ✔✔Is the event consisting of all outcomes in the sample space that are not in event A complement rule - correct answer ✔✔P(A^C)= 1-P(A) A and B are mutually - correct answer ✔✔P(A intersection B)=0, P(A U B)= P(A) + P(B) Conditional Probability - correct answer ✔✔Given two events A and B where P(A)=0 and P(B)=0, P(A | B)= P( A intersection B)/ P(B), P(B | A)= P( A intersection B)/ P(A) addition rule - correct answer ✔✔P (A U B)= P(A) + P(B) - P(A intersection B) A and B are independent - correct answer ✔✔P(A|B)=P(A) or P(B|A)=P(B) multiplication rule - correct answer ✔✔P(A intersection B)=P(A|B)xP(B) and P(B|A)xP(A) multiplication rule for independent events - correct answer ✔✔If A and an are independent events, then P(A intersection B)= P(A) x P(B) Complement Rule - correct answer ✔✔The probability of the complement of an event is equal to one minus the probability of the event The Addition Rule - correct answer ✔✔States that the probability that A or B occurs is equal to the probability that A occurs, plus the probability that B occurs, minus the probability that A and B occurs Conditional Probability - correct answer ✔✔In many situations, the probability of an event occurring is conditional on another event happening event being independent - correct answer ✔✔If the occurrence of one does not affect the probability of the other event two events being dependent? - correct answer ✔✔If the occurrence of one does not affect the probability of the other event
