Question 7
Suppose P(A) represents the probability that a local authority in Namibia will allocate more land to
residents of informal settlements in the year 2023. If P(A) = 0.57, what is the probability that the
local authority will not allocate more land to residents of informal settlements in the year 2023?
[3]
Question 8
The following show the marks obtained by selected Namibian planners in a professional exam: 80, 70,
55, 40, 55, 75, 60, 65, 70 and 55. Calculate the following for the marks:
(a) Mean

Question 9
A survey estimates that the probability of the planning process being inclusive is 0.88. For the
planning processes which are inclusive, 53% are also technologically oriented. What is the
probability that a randomly selected planning process is both inclusive and technologically oriented?

Question 10
Let y represent the number oftimes planners have engaged with the local community over the past
12 months. Assuming that the probability distribution of y is approximately: P(0) = 0.25, P(l) = 0.10,
P(2) =0.45, P(3) =0.15 and P(4) =0.05.
(a) Is ya discrete or a continuous variable? Please explain briefly.

Question 11
As a development planner, you have the task of sampling from the 15,000 residents in a region to find
out the percentage of inhabitants who believe the regional council has been ineffective in delivering

residents.
