If
is true, then
is false, which in turn means
is true.
If
is false, then
is true, and so
is false.
So, because
in both cases, the statement is a tautology (always true).
If you were to put this in a table, you would have one column each for
. In the first column (
) you can think of
as an independent variable that can only take two values, true and false. In the next column (
), you would negate the value in the previous column. And so on.
It should roughly look like this:
p ... ~p ... ~(~p)
T ... F ... T
F ... T ... F

Step-by-step explanation:
The overall reliability of the system provided in design A = 89.13 %
Product design B has higher reliability than design A.
Overall reliability of system provided in design B = 89.85 %.

The measure of the angle PUT is 13 degrees and the measure of the angle PQR = 21 degrees
<h3>What is an angle?</h3>
When two lines or rays converge at the same point, the measurement between them is called a "Angle."
We have triangles shown in the picture.
In the first triangle SUT:
PU is bisecting the angle SUT:
The measure of angle PUT:
Angle PUT = Half of Angle SUT
= 26/2
= 13 degrees
In the triangle SQR:
Angle SQP = Angle PQR
Angle SQP = 21 degrees
Angle PQR = 21 degrees
Thus, the measure of the angle PUT is 13 degrees and the measure of the angle PQR = 21 degrees
