At a city hospital 40 boys and 50 girls were born yesterday. what is the experimental probability that the next baby born will be a girl

around 44%

Step-by-step explanation:

You add 40+50 in order to find the total number of babies born. Only 40 of those 90 were girls. Divide 40 by 90 in order to get the decimal .444444. This is turned into a percentage by moving the decimal place right 2 places.

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.
