Answer: Second option: 8/21
Solution:
P(1) = (Number of times we get 1) / (Total number of results)
Number of times we get 1 = 8
Total number of results = 21
P(1)=8/21
21 line segments are needed to connect each dot to each other dot.
Since, there are 7 dots on a piece of paper such that no 3 dots are in a straight line.
We know that a line segment has two endpoints.
Number of line segments formed by <em>n</em> points = 
So the required number of line segments are needed to connect given 7 dots (each dot to each other dot
)
Hence, 21 line segments are needed to connect each dot to each other dot.

Answer:
4
Step-by-step explanation:
Make a graph.
Start at negative 2 because that's the y intercept. Remember that a minus sign in front of the y intercept just means it's negative.
The slope is basically the rise over the run. How much you go UP divided by how much you run. Since the slope is 3/2, we go up 3 and right 2.
Keep making points and you get 4
The measurement of the second angle is 42°. All of the angles of a triangle add up to a total of 180°. If two angles add up to 138°. Then the last angle has to be 42° (180-138).
