Define sample space
all the possible outcomes

A population is
A census is
A sample is
•Population – every possible element or thing included in the survey e.g. all students in Year 8 at WVSHS – collected using a census
•Census – data collected from an entire population – every 5 years Australia takes part of a census conducted by the Australian Bureau of Statistics
•Sample – representative portion of the population e.g. 30 students in Year 8 at WVSHS – collected using a survey

Explain and identify what the outlier is
7,8,9,9,10,12,14,16, 52
An outlier is data that stands out, it doesn't appear to fit with the rest of the data. - much bigger or smaller than the rest of the data.
The outlier in the data set was 52 as it is significantly larger than the rest of the data set.

The probability of not drawing a black queen from a standard deck of cards is
The complement of drawing a black Queen
p(Not black Q)= 1 - 2/52
p(Not black Q)= 1- 0.038
p(Not black Q) = 0.962 or 96.2 %

Use the Venn diagram to answer the questions
How many people like only hockey?
What is the probability that someone likes gymnastics?
What is the probability that someone likes only hockey b?
What is the probability that someone likes hockey or gymnastics?
What is the probability that someone likes hocky and gymnastics?
What is the probability that someone doesn't like either?
5 people like only hockey
p(gymnastics) = 9/29
P(only hockey) =5/29
p(hockey or gym) = 14/29
p(hockey and gym) =6/29
p( hockey and gym)'=15/29

When surfing, the probability that a wave is surfable is 0.25. The probability that the wave is not surfable is
The complement of a surfable wave
P ( not surfable) = 1 -0.25
P ( not surfable) = 0.75 or 75%

Construct a Venn diagram to represent the following:
Students in a yr 8 class were asked about their fav pets. Of the 26 members of the class, 12 liked cats, 19 liked dogs and 7 liked both.

Construct a two-way table to show all the possible outcomes for flipping a coin and picking a letter from the word MATH and then answer the below:
How many outcomes were in the sample space
what is the probability of getting a head and a consonant?
What is the probability of getting a tail and a vowel?
What is the probability of getting a tail or vowel?
Number of outcomes in sample space: 8
P(head and consonant)= 3/8
P(tail and vowel) =1 /8
P(tail or vowel)= 5/8
