Let’s denote the probability of red as
. According to the relationships given, we can express the probabilities of the other colors in terms of
:
Now we have:
Next, we know that the total probability should equal 1, so we can set up the equation:
This simplifies to:
Thus, we find:
Now we can calculate the probabilities:
Therefore, the probabilities are:
- Green:
- Blue:
- Brown:
- Pink:
- Red:
You can use this information to draw a spinner divided into these sections proportional to the calculated probabilities!
