Question

Let E1 denote the event that a temperature exceeds 58 Celsius, let E2 denote the event that a temperature is less than or equal to 98 Celsius, and let E3 denote the event that a temperature is greater than or equal to 95 Celsius. Describe the following events: find E1​∪E2​

Answer 1

The event (E1 ∪ E2) describes any temperature that is either greater than 58 Celsius or less than or equal to 98 Celsius, which effectively includes all temperatures below or equal to 98 Celsius.

Step-by-step explanation:

To describe the event E1 ∪ E2, we first need to understand what each event represents individually. Event E1 is the temperature exceeding 58 Celsius, and event E2 is the temperature being less than or equal to 98 Celsius.

The union of these two events, denoted by E1 ∪ E2, represents any temperature that is either greater than 58 Celsius or less than or equal to 98 Celsius. Since every temperature above 58 Celsius is also below 98 Celsius, the union effectively includes all temperatures below or equal to 98 Celsius.
