Abag contains: 10 red, 12 green, 15 blue, 8 red, 12 white, and 7 black. a marble is chosen. find the probabilities of choosing

Solution:

Total Number of marbles in the Bag = 10 red, + 12 green,+ 15 blue,+ 8 red, +12 white, + 7 black= 64 marbles

→Probability of an event =

→Probability of choosing a Red Marble from (64 marble=10 R + 12 G + 15 B+8 r + 12 W + 7 B)=

→Probability of choosing a Green Marble from (64 marble=10 R + 12 G + 15 B+8 r + 12 W + 7 B)=

→Probability of choosing a Blue Marble from (64 marble=10 R + 12 G + 15 B+8 r + 12 W + 7 B)=  

→Probability of choosing a red of another kind(r)  Marble from (64 marble=10 R + 12 G + 15 B+8 r + 12 W + 7 B)=

→Probability of choosing a White Marble from (64 marble=10 R + 12 G + 15 B+8 r + 12 W + 7 B)=

→Probability of choosing a Black Marble from (64 marble=10 R + 12 G + 15 B+8 r + 12 W + 7 B)=

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.  

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
