Kimberly is learning probability in middle school while her little brother, Rodney, is learning arithmetic in first grade. Kimberly uses a six-sided number cube to help Rodney learn how to add one-digit numbers.
She rolls two cubes, numbered 1 through 6, and Rodney adds up the two numbers on the faces.
a. Construct a tree diagram to determine all the possible outcomes. List the sum at the end of each
branch of the tree.
b. Construct a probability model for rolling 2 six-sided number cubes and determining the sum of the
faces.
c. What is the probability that the sum is 7?
d. What is the probability that the sum is 11?
e. Calculate the probability that the sum is an even number.
f. Calculate the probability that the sum is greater than 5.
g. What event would be complementary to the event that the sum is greater than 5? Explain your
reasoning.

n

step-by-step explanation:

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
