1. A bag contains 6 red marbles, 6 white marbles, and 4 blue marbles. Find P(red or blue).

p = 5/8

Step-by-step explanation:

6+6+4 = 16

red (6) + blue (4) = 10

p = 10/16

simplify

p = 5/8

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: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
