8. A raffle sold 1500 tickets at $2 a ticket. The first prize is $100 and second prize is $50. Find the expected value for someone who buys one ticket. (3 pts.)

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.
