About 12% of individuals write with their left hands. if a class of 130 students meets in a classroom with 130 individual desks, and 14 of the students write with their left hands, the probability that not all left handed students will have access to a special desk, constructed for people who write with their left hands is

0.1019

Step-by-step explanation:

Probability, p=12%=0.12

Sample size, n=130 students

Those writing with left=14 students

Using the formula for binomial distribution

P(X≤x)=

Substituting 0.12 for p, 130 for n, 14 for x we obtain

P(X≤x)=

P(X≤x)=

P(X≤x)=0.1019

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.
