Week 2

Question 1

Sample Space

Answer 1

Set of all possible experimental outcomes. Discrete or continuous

Question 2

Discrete Sample Space

Answer 2

Finite number of elements. Only certain points between two values

Question 3

Continuous Sample Space

Answer 3

Continuum of elements. All points between two values.

Question 4

Mutually exclusive events

Answer 4

No elements in common, One thing happens the other thing cannot happen

Question 5

Unions

Answer 5

Either element

Question 6

Intersections

Answer 6

Both Elements

Question 7

Complements

Answer 7

Not that element

Question 8

Venn Diagram

Answer 8

uses overlapping circles or other shapes to illustrate the logical relationships between two or more sets of items

Question 9

How do you determine the number of possibilities in a solution?

Answer 9

Number of possibilities determined by multiplication of choices. EX: True/False question with 12 questions would be: 2x2…2=2^12=4096

Question 10

Permutations

Answer 10

Particular Order. nPr=n!/(n-r)! where n>r

Question 11

Combinations

Answer 11

No particular order. (n r)=n!/(r!*(n-r)!)

Question 12

Probability

Answer 12

how likely something is to happen and always measured between 0 & 1. EX: getting a 6 on a dice roll = 1/6

Question 13

Conditional Probability

Answer 13

What is the probability of an even (A) happening given that another event (B) has occurred.

Question 14

Bayes Theorem

Answer 14

Bayes’ Theorem states that the conditional probability of an event, based on the occurrence of another event, is equal to the likelihood of the second event given the first event multiplied by the probability of the first event.
