Aspinner is divided into two equal parts, one red and one blue. the set of possible outcomes when the spinner is spun twice is s = {rr, rb, br, bb}. let x represent the number of times blue occurs. which of the following is the probability distribution, px(x)?

Suppose that the spinner is spun twice. Find the probabilities:

1. When X=0, blue occurs 0 times. There is one favorable outcome (RR) from four possible. Then

2. When X=1, blue occurs 1 times. There are two favorable outcomes (RB and BR) from four possible. Then

3. When X=2, blue occurs 2 times. There is one favorable outcome (BB) from four possible. Then

At last, the distribution table takes look

use formula for the circle a=3.14

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.
