Answers
1
What is a branch in a tree diagram?
A decision point
A probability value
A random event
An outcome path
2
What does a tree diagram represent?
Just one outcome
All possible outcomes
Only probabilities
Random events only
3
Conditional probability is always positive.
False
True
4
Which is a limitation of tree diagrams?
They can be confusing
They are always accurate
They are too simple
They require no math
5
Which is a use of tree diagrams?
To show relationships
To list items
To calculate probabilities
To draw pictures
6
Conditional probability can be calculated using tree diagrams.
False
True
7
What is the formula for conditional probability?
P(A|B) = P(A)
P(A|B) = P(B) / P(A)
P(A|B) = P(A ∩ B)
P(A|B) = P(A ∩ B) / P(B)
8
What does a leaf represent in a tree diagram?
A decision point
A branch split
An event outcome
A probability value
9
Which is a common mistake in tree diagrams?
Ignoring branches
Using wrong labels
Calculating too much
Adding too many branches
10
What is the first step in tree diagrams?
Label events
Draw branches
Calculate probabilities
Identify outcomes
11
Which is a key feature of tree diagrams?
They show sequential events
They are always linear
They require complex math
They are only for statistics
12
Tree diagrams can simplify complex problems.
False
True
13
A tree diagram can show outcomes.
True
False
14
Tree diagrams can help visualize probabilities.
True
False
15
What is the total probability rule?
P(A) + P(B)
P(A) = P(A|B) * P(B)
P(A) = Σ P(A|B) * P(B)
P(A) = P(A ∩ B) + P(B)
16
What does P(A ∩ B) mean?
Probability of neither A nor B
Probability of B only
Probability of A only
Probability of A and B
17
Conditional probability depends on prior events.
True
False
18
Which event is independent?
Traffic conditions
Weather forecast
Coin toss
Stock market
