The probability of pulling a red marble out of a bag of colored marbles is 3: 7. if you were to pull colored marbles out of the bag (one at a time, and putting marble back each time) for 500 tries, approximately how many times would you select a red marble?

Approximately you would select a marble 214 times.

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.  

answer: 270

step-by-step explanation:

you have to times 200 by 1.35 to get your answer
