What actually happens
experimental probability
What is simple probability
One event example: rolling a die
All the possible outcomes of an event is…
The sample space
What is an independent compound event?
two or more events done one after the other that don´t affect each-other
What does he chance 1/4 fall under?
Unlikely
What is expected to happen
Theoretical probability
What is compound probability
two or more events happening at once Example: rolling a dice and spinning a spinner
If you roll a die and flip a coin how many outcomes are there?
12
What is a dependent compound event?
two or more events one after the other that DO affect each-other
What does 1 fall under
Certain
What is the probability of spinning a 2 on a spinner labeled 1-5?
1/5
Is simple probability also compound?
no
If you flip a coin how many outcomes are there?
2
What kind of compound event is picking a marble out of a bag and not putting it back and picking out another that is a different color
dependent
for unlikely and likely does the fraction have to be exactly 1/4 or 3/4?
No as long as its between the 50 mark
If you roll a dice 5 times and record the results what are the results under?
experimental probability
would rolling one dice be simple or compound probability?
simple
How do you calculate the amount of outcomes of a compound event?
you take all the numbers of the events like 6 sides on a dice and multiply them Example: 6 sides of a dice and 2 sides of a coin multiplied together makes 12 outcomes
What kind of event would be getting the ketchup for a hotdog, putting it on the hotdog and then putting back the ketchup for the next person?
independent
All the points on the numberline
impossible, unlikely, as likely as not, likely, and certain
If a fair coin is flipped what is the theoretical probability of it landing on heads?
1/2
Would rolling two dice and getting 1 or 4 on both be compound probability or simple?
compound

Does an independent event have to be compound?
Yes
