What does Michael Breed claim has changed over the<br><br> last 35 years?
Veseljchak [2.6K]

Answer:

Bee colonies are collapsing more frequently than before.

Explanation:

According to a different source, these are the options that come with this question:

Postal workers are getting bitten by bees more than ever.

His neighbors’ bees are destroying his colonies, which has never happened before.

Bees can no longer live in Northern Colorado.

Bee colonies are collapsing more frequently than before.

In this text, the author talks about a man called Michael Breed. Breed is a honeybee researcher at the University of Colorado. He tells us that, in the 35 years that he has been working with bees, he has noticed that bee colonies are collapsing more frequently than ever before. He gives several explanations for this situation, such as more parasites and infections due to climate change, loss of flower scent by pollution or a decreased ability to find a hive due to the use of pesticides.

There are 23 countries in North America, 12 countries in South America, 47 countries in Europe, 44 countries in Asia, 54 countri
natta225 [31]

The probability for each event follows below:

P(A)= 0.23

P(E)= 0.24

P(F)= 0.28

P(N)= 0.12

P(O)= 0.07

P(S)= 0.06

<h3>Probability</h3>

Probability can be defined as the possibility that an event will occur. For an event, the probability can be found from the ratio between the number of favorable outcomes for the event and the total number of outcomes.  Values of probability vary between 0 and 1.

A probability for an event is represented by P(A), P(B), etc. And exactly this that question asks for you.

1. Arrange the text of the question

       North America=23 countries

       South America= 12 countries

       Europe=  47 countries

       Asia= 44 countries

      Africa =54 countries

      Oceania= 14 countries

2. Find the total of countries

N_{total}=23+12+47+44+54+14=194

3. Find P(A)

A= the event that a country is in Asia= 44 countries. Therefore,

P(A)=\frac{numberofcountries of Asia}{Total number of countries } \\ \\ P(A)=\frac{44}{194} =0.23\\ \\ P(A)=0.23

4. Find P(E)

E= the event that a country is in Europe= 47 countries. Therefore,

P(E)=\frac{numberofcountries of Europe}{Total number of countries } \\ \\ P(E)=\frac{47}{194} =0.24\\ \\ P(E)=0.24

5. Find P(F)

F= the event that a country is in Africa= 54 countries. Therefore,

P(F)=\frac{numberofcountries of Africa}{Total number of countries } \\ \\ P(F)=\frac{54}{194} =0.28\\ \\ P(F)=0.28

6. Find P(N)

N= the event that a country is in North America= 23 countries. Therefore,

P(N)=\frac{numberofcountries of North America}{Total number of countries } \\ \\ P(N)=\frac{23}{194} =0.12\\ \\ P(N)=0.12

7. Find P(O)

O= the event that a country is in Oceania= 14 countries. Therefore,

P(O)=\frac{numberofcountries of Oceania}{Total number of countries } \\ \\ P(O)=\frac{14}{194} =0.07\\ \\ P(O)=0.07

8. Find P(S)

S= the event that a country is in South America= 12 countries. Therefore,

P(S)=\frac{numberofcountries of South America}{Total number of countries } \\ \\ P(S)=\frac{12}{194} =0.06\\ \\ P(S)=0.06
