Week 11

Question 1

possible results of observations or experiments, in most basic terms

Answer 1

outcomes

Question 2

one or more outcomes that share a property of interest (HT and TH)

Answer 2

event

Question 3

probability based on assumption that all outcomes are equally likely - number of ways A can occur divided by number of possible outcomes

Answer 3

theoretical method

Question 4

to find the number of possible outcomes for multiple processes combined, multiply the possible outcomes of each individual process to each other

Answer 4

multiplication principle

Question 5

probability found by approximating from observations - number of times A occurred divided by total number of observations

Answer 5

relative frequency method

Question 6

probability estimated based on experience or intuition (qualitative)

Answer 6

subjective method

Question 7

table representing the probabilities of all possible events of interest

Answer 7

probability distribution

Question 8

the ratio of the probability that a particular event will occur to the probability that it will not occur - P(A) divided by P(not A)

Answer 8

odds

Question 9

the occurrence of one event does not affect the probability of the other event occurring

Answer 9

independent events

Question 10

AKA joint probability - probability of two independent events occurring together, found by multiplying their individual probabilities together

Answer 10

and probability

Question 11

occurrence of one event affects the probability of the other event - drawing one from the sample and reducing the total size

Answer 11

dependent events

Question 12

probability that either of two events occurs, rather than both

Answer 12

either/or probability

Question 13

events that cannot occur together (ex. landing on heads and tails at the same time) - mutually exclusive

Answer 13

non-overlapping

Question 14

events that can occur together (ex. queen of clubs is both a queen and a club) - center of Venn diagram

Answer 14

overlapping events
