___________________________________________________________

-11 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0

Okay so on this number line that I made you see -3 degrees F and -11 degrees F. All you have to do is count, start at -3 and count the numbers until you get -11 so the answer would be -8 degrees F because it takes 8 units to get to 7 on the negative number line.

Find the probability that a randomly selected person

Inga [223]

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 E is the ratio of the favorable number of outcomes to the total number of outcomes.

$P(E)=\frac{n(E)}{N}$

Mutually exclusive events are those events which cannot occur together. They are also known as disjoint events.

If events A and B are mutually exclusive then:

$P(A\cap B)=0$

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:

X = a person liked recreational reading.

Y = 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:

$P(X\cup Y)=P(X)+P(Y)-P(X\cap Y)$

$=\frac{176}{200}+\frac{24}{200}-0\\\\=\frac{176+24}{200}\\\\=1$

Thus, the probability that a randomly selected person from this sample liked recreational reading or disliked recreational reading is 1.
