A card is drawn, and we ask the probability it is a king given that it is a face card. This is a:
ACombined proportion
BConfidence interval
CConditional probability
DConstant probability
Answer & Solution
Correct answer: C. Conditional probability
1. Extra information has narrowed the sample space.
2. Only face cards are still in play.
3. That is a conditional probability, written P(A given B).
