As the number of trials in a probability simulation increases (e.g., from 10 to 10,000), what generally happens to the observed relative frequency of an event?

In the coin-flipping game between Peter and Eliott, what is the probability that Eliott wins on his second turn? This occurs if the first three flips (Peter, Eliott, Peter) are all Tails and the fourth flip (Eliott's second turn) is a Head.

True or False: If three events $A$ , $B$ , and $C$ are mutually exclusive and cover the entire sample space $S$ , then their probabilities must sum to 1.

In a sample space ${S}$ , if an event ${A}$ is such that the number of outcomes ${n(A)}$ is equal to the number of outcomes ${n(S)}$ , which of the following must be true?

If two events $A$ and $B$ are defined such that $P(A \cup B) = P(A) + P(B)$ , what must be true about the relationship between $A$ and $B$ ?

It stays exactly the same as it was after 10 trials

It fluctuates more wildly away from the theoretical probability

It always becomes exactly equal to the theoretical probability

It tends to get closer to the theoretical probability
