Using, permutation and combination, the number of ways in which 10 people can be seated in a row, if there are no restrictions on the seating arrangement is 36,28,800, and if elaine and jerry must sit together is 7,25,760.

<h3><u>What is permutation and combination?</u></h3>
  • Combination and permutation are two alternative strategies in mathematics to divide up a collection of components into subsets.
  • The subset's components can be listed in any order when combined.
  • The components of the subset are listed in a permutation in a certain order.
  • There are only a finite number of permutations and combinations for each data set.
  • They can therefore be used to calculate the probability of complex events.
  • The number of possible permutations increases and the likelihood that a particular permutation will occur decreases as a set's elements increase.

The number of ways in which 10 people can be seated in a row without any restriction is 10! = 36,28,800.

Bundle up Elaine and Jerry together. There is now 9 discernible objects multiplied by 2! for the permutations of Elaine and Jerry = 2! * 9!,

The correct answer is identity versus role confusion

 

The fifth stage of Erikson's Psychosocial Development Theory, which takes place between the ages of 12 and 18, takes on different shapes due to the psychosocial crisis that occurs in it, that is, Identity Versus Confusion. In this context, the term crisis does not have a dramatic meaning, as it is something punctual and located with positive and negative poles.

This 5th age is located approximately from 12 to 18/20 years, that is, in adolescence, precisely at the age when in the positive aspect, the adolescent will acquire a psychosocial identity, that is, he understands his uniqueness, his role in world.

The young man experiences a series of challenges that involve his attitudes towards himself, with his friends, with people of the opposite sex, loves and the search for a career and professionalization. As people around you help solve these questions, you will develop a sense of personal identity. If you do not find answers to your questions, you may become disorganized, losing reference.

At this stage, individuals are filled with new cognitive potentialities, explore and rehearse social statutes and roles, due to the society providing this space for experimentation to the teenager. It is in this context that one of the Eriksonian concepts that helps to give so much relevance to this stage stands out, that is, the psychosocial moratorium, a period of pause necessary for many young people, the search for alternatives and the experimentation of roles, which will allow a work of internal elaboration.

Thus, the adolescent anticipates his future, explores alternatives, experiments, takes a break. Personal needs, sociocultural and institutional demands characterize the moratorium.

If a genetically based attraction to beautiful people contributed to survival, that trait will likely be passed on to subsequent
Dennis_Churaev [7]

Answer:

Natural Selection

Explanation:

Genetic variations are one of the most important factors in the evolution of organisms. Mutations are fundamental in this process. When a mutation is produced in an organism, and that mutation produces an 'attractive' trait that will potentially help the organism to reproduce, then, this trait (if the mutation is hereditary) will be passed on to the subsequent generations and will stay in the population as it is beneficial.

This perfectly illustrates natural selection, which refers to a process in which a trait that is advantageous will stay in a given species if it helps the individual to survive and reproduce. In other words, nature "selects" the organisms that possess the 'best' traits so they can pass them from generation to generation and increase their chances of survival.
