Astandard number cube is rolled 216 times.
predict how many times a 3 or a 5 will be the result.

you expect a 3: 216/6 times, and a 5:216/6 times. We add these probabilities together to get the amount of times we get a 3 or 5. 216/6+216/6=432/6=72 times

answer: 20

step-by-step explanation:

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.
