Test 2

Question 1

Probability

Answer 1

Measure of the likelihood that an event will occur

Assigned on a scale of 1-0

Question 2

Random experiment

Answer 2

A process that generates well defined outcomes. Determined by chance

Question 3

Sample space

Answer 3

The set of all experimental outcomes

Question 4

Counting rule for multiple step experiment

Answer 4

If an experiment can be described as a sequence of k steps

Question 5

Counting rule for combinations

Answer 5

Allows us to count the number of experimental outcomes when the experiment involves selecting n objects from a set of N objects

Question 6

Counting for permutations

Answer 6

When n objects are selected from N objects where the order of selection matters

Question 7

Assigning probabilities

Answer 7

Probability assigned must be between 0-1

The duke of the probabilities must be 1

Question 8

Complement

Answer 8

P(A)=1-P(Ac)

Question 9

Mutually exclusive

Answer 9

If they have no sample points in common always equals 0
