**a. Describe the event \( E_1 \cap E_2 \).** In probability and set theory, the event \( E_1 \cap E_2 \) refers to the intersection of events \( E_1 \) and \( E_2 \). This intersection represents all outcomes that are common to both events. In other words, it describes the set of outcomes that simultaneously belong to both \( E_1 \) and \( E_2 \). Understanding the intersection of events is crucial for calculating probabilities that involve multiple conditions or events occurring at the same time. This concept is visually represented using Venn diagrams, where the overlapping region of two circles (representing events \( E_1 \) and \( E_2 \)) illustrates the intersection.
