What are probabilities?
Probabilities are essentially ratios that give the measure of the likelihood of an event happening.
A simple way to set up a probability fraction is by following the equation:
Frequency of event/Total # of outcomes
*Frequency of an event is the value of how many times an even can happen.*
- For A, the counter could possibly be red 6 different times, so 6 would be the numerator in the ratio.
- To find the total number of outcomes, just add all the different values together: 6 + 4 + 8 = 18 so the denominator is 18
A)
or
Follow this same process for B.
Frequency of the counter not being blue= red + green = 6 + 8 = 14
Total # of outcomes= 6 + 4 + 8 = 18
B)
