The ozone layer is an important component of earth’s atmosphere because it helps to block uv radiation from reaching earth. the
Veronika [31]

If ozone layer is completely removed then many severe effects can be seen in the temperature of the earth.

  • The ice in the Antarctica starts getting melt which increases the level of water in ocean and proved to be harmful for the coastal areas.
  • The rise in temperature also lead to long summers and high temperatures ranges from 50° C to 65° C .

Explanation:

The removal of ozone layer will not only effect the temperature but also had a great impact on human and animals such as

  • The harmful rays will directly fall on earth in the absence of ozone cause cancer in animals, plants and humans.
  • These harmful rays weaken the immune system.
  • Lead to disturbance of food chain in following ways : -
  1. It will led to increase in herbivores as a result, the number of plants will decrease and the amount of oxygen will also decrease in the atmosphere.
  2. The carnivores keep the population of other carnivores and herbivores in check. This will disturb the balance of ecosystem.
  3. The concentration of harmful chemicals is maximum at the last trophic level . Because these chemicals are not degradable, these get accumulated progressively at each trophic level.

Find the number of outcomes in the complement of the given event. out of 259259 strawberry plants in a field, 142142 are ready f
Zolol [24]

The number of outcomes in the compliment of the event are 0.54

<h3>Concept and calculation</h3>

No of strawberry plants in the field = 259259

No of plants that are ready for picking = 142142

so no of outcomes = 142142/ 259259 = 0.54 outcomes

<h3>Understanding of probability</h3>

The area of mathematics that deals with probability is called probability theory.

Probability is a concept that can be interpreted in a variety of ways, but probability theory tackles the idea in a rigorous mathematical way by expressing it through a series of axioms.

Typically, these axioms formalize probability in terms of a probability space, which links a collection of outcomes known as the sample space to a measure taking values between 0 and 1. An event is any defined subset of the sample space.
