3.1 experimental and theoretical probability

100

Find the probability of each situation of rolling a six-sided die: What is the probability of rolling a 5?

1/6 

200

Find the probability of each situation of rolling a six-sided die: What is the probability of rolling a 1 or a 2?

2/6 = 1/3

300

Find the probability of each situation of rolling a six-sided die: What is the probability of rolling an odd number?

3/6 = 1/2

400

Find the probability of each situation of rolling a six-sided die: What is the probability of rolling a number greater than 2?

4/6 = 2/3

500

A card is drawn from a pack of 52 cards. What is the probability that the card is a Queen?

4 / 52 = 1 / 13

3.2 Sample Techniques

100

Individuals selected randomly from the entire population

Simple random sampling

200

Groups which represent the population as a whole are surveyed and data is collected for each of them

Cluster sampling

300

The person doing the sampling chooses a sample based on their knowledge of the population, which could be biased

Judgement sampling

400

Only people who are easy to survey are chosen

Convenience sampling

500

Which Terminology is this: A person who collects data for their own use

Primary Data

3.4 two-step/multistep equations

100

2x+7=13    

x = 3

200

3x-6=2x-2

x = 4

300

5(x-2)=4x-3

x = 7

400

15=23-4x    

x = 2

500

3(1-x)=-2(1-x)

x = 1

3.8 Exponent rules

100

write in expanded form: 6³

6 x 6 x 6

200

Write in expanded form: (-3)²

= (-3)(-3)

=9

300

X⁴  x X² = ?

= X⁶

400

(2⁴)² = ?

= 2⁸

500

X - 2² = ?

= X - (2x2)

= x - 4
