Question 1

probability

Answer 1

How likely something will happen.

Question 2

impossible

Answer 2

Cannot happen.

Question 3

certain

Answer 3

Will definitely happen.

Question 4

likely

Answer 4

Will probably happen; more than 50/50

but less than certain.

Question 5

unlikely

Answer 5

Will probably not happen; less than 50/50

but more than impossible.

Question 6

Answer 6

Even chance that either of 2 outcomes will

happen.

Question 7

sample space

Answer 7

All the possible outcomes in an experiment.

Question 8

outcome

Answer 8

Possible result of an experiment.

Question 9

experiment

Answer 9

Something you do over and over that has a

certain set of possible results.

Question 10

conditional probability

Answer 10

Any time you have dependent events.

Question 11

dependent

Answer 11

One event is affected by another event.

Question 12

independent

Answer 12

When the outcome of one event has no
effect on future outcomes.

Question 13

outcome

Answer 13

is the result of a single trial of a probability experiment.

Question 14

Probability

Answer 14

as a general concept can be defined as the chance of an event occurring.

Question 15

A probability experiment

Answer 15

is a chance process that leads to well-defined results
called outcomes.

Answer 19

consists of a set of outcomes of a probability experiment.

Question 20

compound event

Answer 20

The event of getting an odd number
when a die is rolled
