Answer:
Step 1: It should be m∠m + m∠n + m∠o = 180° (sum of angles in a triangle)
Step-by-step explanation:
He made the mistake in Step 1: m∠m + m∠n + m∠p = 180°
It should be m∠m + m∠n + m∠o = 180°
Then only, he can equate it with m∠o + m∠p in step 3.
So, m∠p is the exterior angle and m∠m and m∠n are the two remote interior angles.
m∠o is the adjacent angle to m∠p. They form a linear pair.
Hence, the correct answer is Step 1.

Answer:
x=-4
Step-by-step explanation:
n has less than 75 copies
sold 12
so add the 12 back
n had less than 87 copies in the beginning of the day

<span>P<span>(S∪T)</span>=<span>34</span></span>
Explanation:
We use the following fundamental definition from Probability and Set Theory:
<span>P<span>(A∪B)</span>=P<span>(A)</span>+P<span>(B)</span>−P<span>(A∩B)</span></span>
And if we apply this to our problem we have:
<span>P<span>(S∪T)</span>=P<span>(S)</span>+P<span>(T)</span>−P<span>(S∩T)</span></span>
<span> =<span>13</span>+<span>512</span>−P<span>(S∩T)</span></span>
<span> =<span>34</span>−P<span>(S∩T)</span></span>
Now we are told that S and T are mutually exclusive, and so:
<span>P<span>(S∩T)</span>=0</span>
Hence,
<span>P<span>(S∪T)</span>=<span><span>34</span></span></span>
