To solve this problem, let us first define what
probability means in this case. It would be:
Probability = (number of colors to choose from) / (total
number of colors)
There are a total of 5 colors on the spinner. The number
of colors to choose from spins 1 to 8 would be 5 out of 5, while for the last
spin 9 the number of colors to choose from would only be brown so that would be
1 out of 5. The total probability would be the product of the probability of
each spins, therefore:
Probability = 1st spin * 2nd spin * 3rd
spin * 4th spin * 5th spin * 6th spin * 7th
spin * 8th spin * 9th spin
Probability = (5/5) *(5/5) *(5/5) *(5/5) *(5/5) *(5/5) *(5/5)
*(5/5) * (1/5)
Probability = 0.2
There is a 20% chance to get brown on the last spin.
