Suppose that 80% of books are classified as fiction. Two books are chosen at random. What is the probability that both books ara fiction?

Answers

Answer 1

Answer:

64% or 16/25

Explanation:

To calculate probability, we first find the fraction for the number of books that are fiction.

[tex]80= \frac{4}{5}[/tex]

To find out what the probability of choosing a fiction book twice, we multiply 4/5 with 4/5 to get our probability if we selected a book twice.

[tex]\frac{4}{5} *\frac{4}{5} = \frac{16}{25} \\0.64[/tex]

The probability of choosing two fiction books is a 16/25, or 64% chance.

Round to two decimal places as needed.)

Answers

Answer:

The probability that the child will have red hair color is 0.75.

Thus, the probability that a child of these parents will have the blond / blond genotype is 0.25.

Explanation:

It is provided that each parent has the genotype red / blond which consists of the pair of alleles that determine hair color, and each parent contributes one of those alleles to a child.

The possible outcomes for the hair color of the child are:

S = {R/R, R B, B/R and B/B}

There are four possible outcomes.

Compute the probability that the child will have red hair color as follows:

[tex]P(\text{R})=P(\text{R/R})+P(\text{R/B})+P(\text{B/R})[/tex]

         [tex]=\frac{1}{4}+\frac{1}{4}+\frac{1}{4}\\\\=\frac{3}{4}\\\\=0.75[/tex]

Thus, the probability that the child will have red hair color is 0.75.

Compute the probability that a child of these parents will have the blond / blond genotype as follows:

[tex]P(\text{B/B})=\frac{1}{4}=0.25[/tex]

which point on a graph shows minimum wage as the price floor

Answers

Answer:

For a price floor to be effective, the minimum price has to be higher than the equilibrium price. ... The most common example of a price floor is the minimum wage. This is the minimum price that employers can pay workers for their labor. The opposite of a price floor is a price ceiling.

Explanation:

A price floor or a minimum price is a regulatory tool used by the government. More specifically, it is defined as an intervention to raise market prices if the government feels the price is too low. In this case, since the new price is higher, the producers benefit. For a price floor to be effective, the minimum price has to be higher than the equilibrium price.

For example, many governments intervene by establishing price floors to ensure that farmers make enough money by guaranteeing a minimum price that their goods can be sold for. The most common example of a price floor is the minimum wage. This is the minimum price that employers can pay workers for their labor.

What can companies hope to gain from a sponsorship deal? A. lots of free samples B. products, services, and direct financial support C. the opportunity to meet some famous celebrities D. to fly on the sponsor’s private jet

Answers

Answer:

I believe the correct answer is B. products, services, and direct financial support

Explanation:

Answer C and D do not make sense, and answer A is not logical

hope this helps :)

Companies can hope to gain products, services, and direct financial support from a sponsorship deal. The correct option is B.

What is sponsorship deal?

A sponsorship deal is an agreement between a sponsor and a sponsee in which the sponsor provides financial or other support to the sponsee in exchange for some form of promotion or exposure.

A sponsorship agreement can provide companies with products, services, and direct financial support.

This is due to the fact that most sponsorship agreements involve a company providing financial or other resources to a person, organisation, or event in exchange for some form of promotion or exposure.

This promotion or exposure can include things like product placement, brand visibility, and advertising opportunities, all of which can help increase brand awareness and sales for the company.

While companies may receive free samples or the opportunity to meet celebrities as part of a sponsorship agreement, these are usually not the primary goals of such agreements.

Thus, option B is the best choice.
