Is rolling an even number on a cube an outcome or an event?
It is an event because it is a collection of several outcomes.
100
Explain how to find the probability of an event.
The probability of an event is the ratio of the number of favorable outcomes to the number of possible outcomes.
100
Describe how to find the experimental probability of an event?
Perform an experimental several times. Count how often the event occurs and divide by the number of trials.
100
What is the sample space of an event? How can you find the sample space of two or more events?
A sample space is the set of all possible outcomes of an event. Use a table or tree diagram to list all the possible outcomes.

Are many possible results are there on a spinner with numbers 1-8 on it?
8 because there are 8 numbers.
200
Can the probability of an event be 150%? Explain.
No, because the highest percent you can have is 100%. Certain.
200
An event has a theoretical probability of 0.5. What does this mean?
There is a 50% chance you will get a favorable outcome.
200
Now you guess the correct answer in 5 times. What is the probability of that happening?
5/1000

How many bananas can you eat if your stomach is empty?
1, because after you eat that one your stomach isn't empty.

What are the possible outcomes of randomly choosing one of the numbers below?
1,2,3,4,5,6,7,8,9
1,2,3,4,5,6,7,8,9

Give a real life example of an event that is impossible. Give a real life example of an event that is certain.
Impossible- You have a pet dinosaur.
Certain- You are a human.

Describe an event that has a theoretical probability of 1/4
There are 8 letters. Two of them are vowels. The probability to pick a vowel is 1/4.

What starts with a P, ends in a E and has thousands of letters?
A post office.

A spinner has 4 sections. 1 blue, 1 red, 1 green, and 1 orange. What percentage do you have on landing on blue?
25%.

Describe the likelihood of the event given.
Your soccer team wins 3/4 of the game.
Likely.

Describe an example of experimental probability.
You roll a dice 50 times. What is the experimental probability of rolling an odd number. You roll a 1 10 times, a 3 8 times, and a 5 11 times. 10+8+11=29= 29/50

How do you use the fundamental counting principle?
An event M has m possible results. An event N has n possible results. The total number of outcomes of event M followed by event N is m*n

What do you throw out when you need it ,but take it when you don't need it?
An anchor.

Explain how an outcome and a favorable outcome are different.
An outcome is a possible outcome for anything, but a favorable outcome is a possible outcome for a specific event.
500
You have a 0% chance of growing 20 feet in a year.
Impossible.

What is the experimental probability of rolling an odd number. When you roll the dice 300 times. You roll a 1 48 times, a 3 50 times, and a 5 49 times.
48+50+49=147= 147/300
