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.

Which expression is equivalent to 36^-1/2

inn [45]

ANSWER

$( {36})^{ (- \frac{1}{2}) } = \frac{1}{6}$

EXPLANATION

The given expression is

${36}^{( - \frac{1}{2} )}$
This is having a negative index. We must first of all change to a positive index.

Recall that,

${a}^{ - m} = \frac{1}{ {a}^{m} }$

We apply this law of exponents to get,

${36}^{( - \frac{1}{2} )} = \frac{1}{ {36}^{( \frac{1}{2} )} }$

We cab rewrite the given expression to obtain;

${36}^{( - \frac{1}{2} )} = \frac{1}{ \sqrt{36} }$

This will simplify to give us,

${36}^{( - \frac{1}{2} )} = \frac{1}{ 6 }$

when ashley buys 7 postage stamp booklets she gets 140 stamps.she get 60 stamps in three booklets. write an equation to find the

Andreyy89

We can put this information into two equations:

7 booklets = 140 stamps
3 booklets = 60 stamps

Let us then focus on one equation to find the relationship:

7 booklets = 140 stamps

If we put that into a fraction, we get $\frac{7}{140}$ or $\frac{1}{20}$ .

This means that for every booklet, Ashley gets 20 stamps; or rather, each booklet has 20 stamps.

We can then see that this relationship holds true for the second equation as well:

$\frac{3}{60}$ or $\frac{1}{20}$ .

To write a general equation for this relationship using p for the number of postage stamps, and b for the number of booklets:

p = 20b

Where b is equal to p.
