Instructions
Click the spin button 10 times above on the spinner to find your experimental occurrences. Based on your results, answer the questions below. Note: There will be one group question!
Experimental probability
When you perform an experiment a number of times, the fraction or percentage of times that a given event occurs is called the empirical probability or experimental probability of that event.
Formula:
P = number of times the event is occurring
total number of trials of the experiment.
Based on your experiment, what was the probability of landing on yellow?
Based on your experiment, what is the probability of NOT landing on blue?
Based on your experiment, what was your GROUPS probability of landing on green?
Theoretical Probability
The theoretical probability of a given event is a number
quantifying how likely that event is; it is the fraction or percentage of
times that event should occur in the ideal.
Formula:
P(S) = the number of outcomes in S
the number of total outcomes possible
