Answer:
The probability that a randomly selected person from this sample liked recreational reading or disliked recreational reading is 1.
Step-by-step explanation:
The probability of an event <em>E</em> is the ratio of the favorable number of outcomes to the total number of outcomes.
![P(E)=\frac{n(E)}{N}](https://tex.z-dn.net/?f=P%28E%29%3D%5Cfrac%7Bn%28E%29%7D%7BN%7D)
Mutually exclusive events are those events which cannot occur together. They are also known as disjoint events.
If events <em>A</em> and <em>B</em> are mutually exclusive then:
![P(A\cap B)=0](https://tex.z-dn.net/?f=P%28A%5Ccap%20B%29%3D0)
The data provided is:
Opinion Like academic Dislike academic Total
reading reading
Liked recreational 136 40 176
reading
Disliked recreational 16 8 24
reading
Total 152 48 200
Denote the events as follows:
<em>X</em> = a person liked recreational reading.
<em>Y</em> = a person disliked recreational reading.
Compute the probability that a randomly selected person from this sample liked recreational reading or disliked recreational reading as follows:
![P(X\cup Y)=P(X)+P(Y)-P(X\cap Y)](https://tex.z-dn.net/?f=P%28X%5Ccup%20Y%29%3DP%28X%29%2BP%28Y%29-P%28X%5Ccap%20Y%29)
![=\frac{176}{200}+\frac{24}{200}-0\\\\=\frac{176+24}{200}\\\\=1](https://tex.z-dn.net/?f=%3D%5Cfrac%7B176%7D%7B200%7D%2B%5Cfrac%7B24%7D%7B200%7D-0%5C%5C%5C%5C%3D%5Cfrac%7B176%2B24%7D%7B200%7D%5C%5C%5C%5C%3D1)
Thus, the probability that a randomly selected person from this sample liked recreational reading or disliked recreational reading is 1.

Answer:
k = -1/5
Step-by-step explanation:
3k +2k +1 = 0
5k +1 = 0
5k = 0 -1
5k = -1
k = -1/5
