2.5 Relative Frequency
The table shows the relative frequency of a 5 sided spinner.
1. How many times would you expect the spinner land on the blue side if
you spun the spinner 200 times?
A probability of 0.3 is means that the spinner will land on the blue side 30% of the time.
2. If the probability of the black and the yellow are equal, what are their probabilities.
