4. Determine whether the events are mutually exclusive. Then determine whether the events are independent or dependent. Explain your reasoning.
Event A: A bowler having the highest game in a 40-game tournament
Event B: Losing the bowling tournament

Step 1: Define mutually exclusive events. Mutually exclusive events are events that cannot occur at the same time. For example, if one event happens, the other cannot happen. Analyze whether Event A (having the highest game) and Event B (losing the tournament) can occur simultaneously.
Step 2: Evaluate whether Event A and Event B are mutually exclusive. Consider if it is possible for a bowler to have the highest game in a tournament but still lose the tournament. If this is possible, the events are not mutually exclusive. If it is not possible, the events are mutually exclusive.
Step 3: Define independent and dependent events. Independent events are events where the occurrence of one event does not affect the probability of the other event occurring. Dependent events are events where the occurrence of one event affects the probability of the other event.
Step 4: Assess whether Event A and Event B are independent or dependent. Consider whether having the highest game (Event A) affects the likelihood of losing the tournament (Event B). If the outcome of one event influences the other, the events are dependent. If not, they are independent.
Step 5: Summarize your reasoning. Based on the analysis of mutual exclusivity and independence, explain your conclusions about the relationship between Event A and Event B. Provide logical justification for your determination.

Mutually Exclusive Events

Mutually exclusive events are those that cannot occur at the same time. In the context of the question, if Event A (a bowler having the highest game) occurs, it implies that the bowler cannot simultaneously lose the tournament (Event B). Therefore, these two events are mutually exclusive.

Probability of Mutually Exclusive Events

Independent Events

Independent events are those where the occurrence of one event does not affect the probability of the other event occurring. In this case, if a bowler has the highest game, it does not influence the outcome of losing the tournament, as the highest score does not guarantee winning. Thus, these events are dependent on each other.

Probability of Multiple Independent Events

Dependent Events

Dependent events are those where the outcome of one event affects the outcome of another. In this scenario, if a bowler has the highest game, it is likely that they would not lose the tournament, indicating a relationship between the two events. This dependency suggests that the events are not independent.

The table shows the results of a survey in which 3,545,286 public and 509,168 private school teachers were asked about their full-time teaching experience.

Are the events “being a public school teacher” and “having more than 20 years of full-time teaching experience” independent? Explain.
