Answer:
For this case we have a total of 10 nonfiction books and 8 fiction books, we are going to assume that the selection is without replacement so then for the first case the probability of select a fiction book is:
For the second selection we have 17 books remaining and the probability of select a nonfiction book is:
For the last selection we have 16 books remaining and the probability of select a fiction book would be:
Sinally since the events are independent the total probability would be:

Answer:
Therefore,
The Central Angle is 48°.
Step-by-step explanation:
Given:
Circumference = 12 units
To Find:
Central angle = θ = ?
Solution:
If "θ" the central angle is in degree then arc of length is given by
Substituting the values we get
Therefore,
The Central Angle is 48°.
