Question

an expert witness can give an opinion in which of the following situations? (choose all that apply.)
□ a. the opinion, inferences, or conclusions depend on special knowledge, skills, or training not within the ordinary experience of laypeople.
□ b. the witness has been shown to be qualified as a true expert in the field.
□ c. the witness testifies to a reasonable degree of certainty (probability) about their opinion, inference, or conclusion.
□ d. hypothetical questions of a witness can only apply to particular situations.

Explanation:

Expert witness opinions are admissible when three core conditions are met: 1) The opinion relies on specialized knowledge beyond lay understanding, as laypeople cannot form such conclusions on their own. 2) The witness is properly qualified as an expert in the relevant field, establishing their credibility to offer specialized insights. 3) The opinion is stated with a reasonable degree of certainty, ensuring it is grounded in professional rigor rather than speculation. Option d is incorrect because hypothetical questions for expert witnesses are not limited to only particular situations; they can be used more broadly to explore expert analysis.

Answer:

a. The opinion, inferences, or conclusions depend on special knowledge, skills, or training not within the ordinary experience of laypeople.
b. The witness has been shown to be qualified as a true expert in the field.
c. The witness testifies to a reasonable degree of certainty (probability) about their opinion, inference, or conclusion.
