when two or more events can occur concurrently it is called\na. a tree diagram.\nb. joint probability.\nc. empirical probability.\nd. conditional probability.
Answer
Brief Explanations:
- A tree diagram is a visual tool for mapping event sequences, not concurrent events.
- Empirical probability is based on observed data frequencies.
- Conditional probability focuses on events dependent on prior outcomes.
- Joint probability describes the likelihood of two or more events happening at the same time, matching the question's definition.
Answer:
b. joint probability.
