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
A prediction
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

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
