Question 1

Random trial

Answer 1

a process/experiment that has 2 or more possible outcomes whose occurrence cannot be predicted

Question 2

Sample space

Answer 2

list of all possible outcomes of a random trial

Question 3

Event

Answer 3

any potential subset of the sample space

Question 4

Probability

Answer 4

(of an event) the proportion of times the event would occur if we repeated a random trial over and over again under the same conditions

Question 5

How are 2 events mutually exclusive?

Answer 5

if they cannot both occur simultaneously

Question 6

Probability distribution

Answer 6

list of probabilities of all mutually exclusive outcomes of a random trial

Question 7

Discrete probability distribution

Answer 7

gives the probability of each possible value or outcome of a discrete variable; measured by height of bar

Question 8

Continuous probability distribution

Answer 8

distribution curve whose height is the “probability density” that allows us to describe the probability of any range of values; measured by area under curve

Question 9

Conditional probability

Answer 9

probability of an event given that another event occurs
