2. Now suppose a single card is draw from a standard 52 card deck, but we are told the card is a heart. What is the probability that the card drawn is a king?

3. Did the knowledge that the card is a heart change the probability that the card was a king?

4. What is the term used to describe this result?

Any input will be assisted. Want to make sure I understand everything correctly. This is what I got:

1. A standard deck of cards has 4 kings so N(E) = 4. P(king) = P(E)= N(E)/N(S)=4/52 = 1/13

2. Probability remains the same. 1/13

3. No.

4. Disjoint. When 2 events have no outcomes in common. Two events are disjoint if they cannot occur at the same time. Another name for disjoint events is mutually exclusive events.
