Question
**Probability Model for Coffee Consumption** Consider an adult aged 18 or over in the United States, randomly selected and asked, "How many cups of coffee do you drink on average per day?" Let \( X \) represent the response. Based on a large sample survey, the probability model for the responses is presented in the table below. | Number of Cups (X) | Probability | |---------------------|-------------| | 0 | 0.36 | | 1 | 0.26 | | 2 | 0.19 | | 3 | 0.08 | | 4 or more | 0.11 | **Expression of Events in Terms of \( X \):** (c) Express the event "have at least one cup of coffee on an average day" in terms of \( X \). - ○ \( X = 1 \) - ● \( X \leq 1 \) - ○ \( X \geq 1 \) - ○ \( X > 1 \) - ○ \( X < 1 \) **Question:** What is the probability of this event? Provide your answer to two decimal places. Probability: _______
