Answer:

Step-by-step explanation:
Given
Let

So:
--- probability of O
--- Number of spin
Using the complement rule, the probability that a spin will not land on orange is:


Express as decimal


On two spins, the probability that it will not land on orange is:

So, we have:


<em></em>
<em> --- approximated</em>
If using the radius, you would multiply the radius by 2*pi, to calculate the circumference, which should be the same as the answer i got.
For this question you can say:
154/11 = 252/?
so ? is the hours she would work:
252*11/154 = 18 hours :)))
i hope this is helpful
have a nice day
