The document discusses using the Addition Rule to calculate the probability of drawing either a 4 or an ace from a standard 52-card deck. It states that the probability of drawing a 4 plus the probability of drawing an ace is equal to the total probability, since a card cannot be both a 4 and an ace. It then shows the calculation of 4/52 + 4/52 = 8/52 = 2/13 = 0.154, which is the 15.4% probability of drawing either a 4 or an ace.

Conditional Probability
- 2. You select a card form a standard deck of 52 cards. Find the probability that the card is a 4 or an ace. If the card is a 4, it cannot be an ace. Use the Addition Rule to find the probability!
- 3. P(a or b) = P(a) + P (b) – P(a and b) If the events are mutually exclusive you may simplify the rule into…P(a or b) = P(a) + P(b) P(4 or Ace) = P(4) + P(Ace) = 4/52 + 4/52 = 8/52 = 2/13 = 0.154
- 4. As you can see…the Addition Rule helped me find the answer by adding the two Fractional Integers then simplifying the sum! The probability that the card drawn is either a 4 or an Ace is 0.154 !!! Or 15.4%
