We are given the following information in the question:
We may define line as:
- A line is a straight one-dimensional figure having no thickness and extending infinitely in both directions.
- A line is sometimes called a straight line.
- It is demonstrated by arrow on both sides showing that it can be extended on both sides.
- A line can be considered undefined term because it tells us about something that does not have width or depth.

Answer:
a) 0.8333
b) 0.75
c) 0.8181 or 0.9090
Step-by-step explanation:
a)
The probability the visitor selects an authentic painting is
10/12 = 0.8333
b)
Since the opinion of the expert does not depend on your choice, the events are <em>independent</em>, so the probability that the expert says is authentic and it really is, is
0.8333*0.9 = 0.75
c)
If the expert decides the painting is a copy and it is not, then there are 11 paintings of which 9 are authentic, so the probability the visitor selects a new original painting is
9/11= 0.8181
If the expert decides the painting is a copy and it is, then there are 11 paintings of which 10 are authentic, so the probability the visitor selects a new original painting is
10/11= 0.9090
