Let X represent the number of homes a real estate agent sells during a given month. Based on previous sales records, she estima
tes that Upper P (0 )equals 0.60, Upper P (1 )equals 0.23, Upper P (2 )equals 0.11, Upper P (3 )equals 0.04, Upper P (4 )equals 0.02, with negligible probability for higher values of x. a. Explain why it does not make sense to compute the mean of this probability distribution as (0 plus 1 plus 2 plus 3 plus 4 )divided by 5 equals 2.0. b. Find the correct mean and interpret.

Part 1)
Part 2)
Step-by-step explanation:
Part 1) Find the measure of angle CQJ
we know that
The measure of the interior angle is the semi-sum of the arcs comprising it and its opposite.
substitute the values
Part 2) Find the measure of angle LIJ
step 1
Find the measure of angle IJL
we know that
The inscribed angle is half that of the arc it comprises.
substitute the values
step 2
Find the measure of angle ILJ
we know that
The measurement of the external angle is the semi-difference of the arcs it encompasses.
substitute the values
step 3
Find the measure of angle LIJ
Remember that the sum of the interior angles of a triangle must be equal to 180 degrees
In the triangle LIJ
substitute the values
