ENSF 461 MIDTERM PRACTICE
EXAMINATION 2026 QUESTIONS
WITH ANSWERS GRADED A+
◍ 6 Parts of LA Focus.
Answer: 1. Climate and Biodiversity 2. Cultural Landscapes3. DEI4. Health
and Wellbeing5. Parks and Recreation6. Transportation7. Stormwater
Management
◍ When do I use permutations vs. combinations?.
Answer: Use permutations when the order of selection matters; use
combinations when it does not.
◍ How do I know when to use complementary counting vs. direct counting?.
Answer: Use complementary counting when 'at least one' appears or when
direct counting requires many cases.
◍ U.S Professional organization for LA's.
Answer: ASLA, Continuing the profession
◍ Why does disjointifying AU BUC give AU (B \ AB) U (C \ AC \ BC)?.
Answer: We need the three pieces to be truly disjoint; removing overlaps
ensures no shared elements.
◍ 4 things to earn and maintain licensure.
Answer: 1. LAAB Accredited Degree2. Apprenticeship3. Registration
Exam4. Continuing Education
◍ 16th Century Concepts.
Answer: (BOTHA)Boundary Occupying SpaceTransitionHarmonyAxial
Symmetry
◍ 17th Century Concepts.
, Answer: (SESHI)ShakkeiExtensionSubdivsionHide and RevealIllusion
◍ 18th Century Summary.
Answer: (FANVO)FramingAllusionNarrativeVarietyObservation
◍ In committee or handshake problems, why doesn't order matter?.
Answer: The committee {Alice, Bob, Carol} is the same regardless of order;
outcomes are sets, not sequences.
◍ How do I keep P(A|B) and P(B|A) straight?.
Answer: P(A|B) is the probability of A given B; the event after the bar is the
given information.
◍ When do I use the law of total probability vs. Bayes' theorem?.
Answer: Use the law of total probability for P(A) with known P(A|B); use
Bayes to flip conditioning.
◍ 19th Century Summary.
Answer: (COATI)CollaborationObservationAccessibility
TransformationIdentity
◍ Why aren't the throws in the die A/die B problem independent?.
Answer: Knowing one throw's outcome affects the choice of die, influencing
future throws.
◍ Does conditioning on more information always change the probability?.
Answer: No, if A and B are independent, P(A|B) = P(A); conditioning
changes probability only if events are dependent.
◍ 20th Century Summary.
Answer: (TUCOI)TruthUtilityCorrespondenceOriginalityIntegrity
◍ Regenerative Design.
Answer: Restoring Ecosystems and Human Communities
◍ If P(ANB) = P(A)P(B), does that make A, B, C mutually independent?.
Answer: No, mutual independence requires the product rule for all subsets,
not just pairs.
