Step-by-step explanation:
The probability of an event , E, happening is:
P(E) = Number of E/ Total Number
Here, we are considering a spinner with sections in color. We want probability that spinner lands on green. So we will need:
Number of divisions of spinner that is green, and
Number of total divisions in the spinner
We will then divide.
Now, from the problem, we are told that there are a total of 15 divisions. And out of those 15, three of them are green, thus:
Number of divisions that are green = 3
Total number of divisions = 15
Thus, the probability would be [let "G" be the event that spinner lands on green]:
P(G) =![\frac{3}{15}=\frac{1}{5}](/tpl/images/0386/1569/61565.png)
This is the probability.
