Question

in a probability tree, what does each branch represent?
a. an independent variable
b. a possible outcome
c. a constant probability
d. an undefined event

Explanation:

A probability tree is a visual representation used in probability. Each branch of the tree shows a possible result or outcome of an event. For example, when flipping a coin (an event), the two branches would represent the two possible outcomes - heads or tails. An independent variable is a variable that is manipulated in an experiment (not related to branches in a probability tree). A constant probability would imply a fixed probability value (branches show outcomes, not just probabilities). An undefined event is not what a branch represents as branches are for defined possible results.

Answer:

b. A possible outcome
