1)
The bisector is the midpoint of the curved line. To find it, place the compass at point A. Open it and draw an arc on both sides.
Without altering the compass, place it at point B and draw arcs on both sides to intersect the previous arcs.
Mark the two points of intersection. Draw a line touching both points. The point where the line touches line AB is the bisector
The sample is shown below
Point C is the bisector

Answer:
P(X = 0) = 0.0208, P(X = 1) = 0.2484, P(X = 2) = 0.7308
Step-by-step explanation:
Let's define the following events
A: the first component meet specification
B: the second component meet specification
P(A) = 0.87
P(B) = 0.84
Let X be the random variable that represents the number of components in the assembly that meet specifications. Because there are only two mechanical components in the assembly, X can only take the values 0, 1, 2.
P(X = 0) = P(the first component does not meet specification and the second component does not meet specification) =
(because of independence)
= (0.13)(0.16) = 0.0208
P(X = 1) = P(only one component meet specification) = P[(the first component meet specification and the second component does not meet specification) or (the first component does not meet specification and the second component meet specification)] =
(because sets are mutually exclusive)
(because of independence)
= (0.87)(0.16) + (0.13)(0.84) = 0.2484
P(X = 2) = P(both components meet specifications) =
(because of independence)
= (0.87)(0.84)
= 0.7308
