None of the scenarios depict mutually exclusive events.

Solución

To determine which scenario depicts mutually exclusive events, we need to analyze each option. Mutually exclusive events are those that cannot occur at the same time. 1. **Begins with a \( J \) and contains a \( u \)**: - The months that begin with \( J \) are January, June, and July. - Among these, only June contains a \( u \). - This scenario is not mutually exclusive since it can occur with just one month (June). 2. **Ends with an \( r \) and has five or fewer letters**: - The months that end with \( r \) are either September or October, but both have more than five letters. - Therefore, this scenario does not apply to any month, making it irrelevant for mutual exclusivity. 3. **Has thirty-one days and ends with a \( y \)**: - The months with thirty-one days are January, March, May, July, August, October, and December. - Among these, only January and May end with a \( y \). - This scenario is not mutually exclusive since it can occur with two months (January and May). 4. **Contains an \( e \) and has thirty or fewer days**: - The months with thirty or fewer days are February, April, June, September, and November. - Among these, February, April, and September contain an \( e \). - This scenario is not mutually exclusive since it can occur with three months (February, April, and September). After analyzing all scenarios, none of them depict mutually exclusive events since each scenario can occur with at least one month. Thus, the answer is that **none of the scenarios depict mutually exclusive events**.

The Deep Dive

Let's dive into some fascinating historical context! The concept of months has roots deep in Roman history. The Julian calendar, introduced by Julius Caesar in 45 B.C., established the basis for our current system and named the months, many of which are still in use today. Interestingly, the names July and August were later added to honor Julius Caesar and Emperor Augustus, respectively, showcasing how days and months have always intertwined with the rulers of the time. For a real-world application to spice things up, let’s consider planning a birthday party! If your friend’s birthday falls in June (which gives you the vibe of summer fun!), you could randomly draw the months to figure out if your party planning aligns with a month that starts with 'J'. When making decisions like this, it’s great to have a clear understanding of what events can occur without overlapping—like choosing a month for all your party planning without worrying about conflicting schedules!
