Astudent randomly chooses every answer on a 30 question multiple choice test which of the following reasons is needed to determine if this is a binomial distribution

Answer-

D. The outcomes can be divided into two categories i.e correct and incorrect.

Solution-

Conditions for applying Binomial Distribution-

In the question it is given that the student randomly chooses every answer on a 30 question multiple choice test, so

Therefore, the correct option should be the option D The outcomes can be divided into two categories i.e correct and incorrect.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
