3.1 experimental and theoretical probability
Find the probability of each situation of rolling a six-sided die: What is the probability of rolling a 5?
1/6
Individuals selected randomly from the entire population
Simple random sampling
2x+7=13
x = 3
5 millimeters = 0.5 Centimeters
write in expanded form: 63
6 x 6 x 6
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
Groups which represent the population as a whole are surveyed and data is collected for each of them
Cluster sampling
3x-6=2x-2
x = 4
9 feet = 3 yards
Write in expanded form: (-3)2
= (-3)(-3)
=9
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
The person doing the sampling chooses a sample based on their knowledge of the population, which could be biased
Judgement sampling
5(x-2)=4x-3
x = 7
10 pints = ___ Gallons
10 pints = 1.25 Gallon
X4 x X2 = ?
= X6
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
Only people who are easy to survey are chosen
Convenience sampling
15=23-4x
x = 2
12 Liter = ____ Pints
12 Liter = 25.36 Pints
(24)2 = ?
= 28
A card is drawn from a pack of 52 cards. What is the probability that the card is a Queen?
4 / 52 = 1 / 13
Which Terminology is this: A person who collects data for their own use
Primary Data
3(1-x)=-2(1-x)
x = 1
140 Gram = ___ Ounces
140 Gram = 4.938 Ounces
X - 22 = ?
= x - 4
