Anumber cube is rolled and a coin is tossed. what is the probability that a number greater than four is rolled and the coin comes up heads?

there are 6 numbers on a cube

there are 2 numbers greater than 4

 so a 2/6 reduced to 1/3 probability

there is a 1/2 probability of getting heads

1/3 x 1/2 = 1/6 probability of getting the wanted results

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.
