One popular way to study probability is to roll dice. A standard die has six sides printed with little dots numbering 1, 2, 3, 4, 5, and 6. If the die is fair (and we will assume that all of them are), then each of these outcomes is equally likely. Since there are six possible outcomes, the probability of obtaining any side of the die is 1/6. The probability of rolling a 1 is 1/6, the probability of rolling a 2 is 1/6, and so on. The probability table of rolling two dice is above:

Two six-sided dice are rolled. What is the probability that the sum of the two dice is seven? Are these results considered Experimental Probability or Theoretical Probability?

• 1/3 and Theoretical probability

• 1/6 and Theoretical probability

• 1/6 and Experimental probability

• 6/18 and Experimental probability

On April 15, 1912, the Titanic struck an iceberg and rapidly sank with only 710 of her 2,204 passengers and crew surviving. Data on survival of passengers are summarized in the table above:

If one of the passengers is randomly selected from the first class passengers, what is the probability that this passenger survived? (That is, what is the probability that the passenger survived, given that this passenger was in first class?)

• 201/324

• 201/1317

• 201/500

• 500/1317
