Answer number 3
Step-by-step explanation:
The <em>correct answer</em> is:
Place the point of the compass on the vertex of our original angle. Open the compass to a random width and draw an arc through both legs of the angle. Mark the points of intersection with this arc and the sides of the angle.
Explanation:
In order to copy the angle, we need to have some reference for how wide the angle is.
So far all we have is a ray. To get the reference for the width that we need, we will construct an arc in the original angle such that it intersects each side of the angle.
We will then set the compass width to these points of intersection. This will be how we set the width of the new angle.
Solution:
A coin is flipped three times,resulting three heads in a row.
Since Steve has mentioned that , each flip of a coin is unconnected to the previous flip.
Two or more events are said to be independent if occurrence of one of them is not affected by the Occurrence of other.
This is an example of independent events.
In terms of probability, P (A∩B∩C)= P(A)×P(B)×P(C)
