In 2015, over 30,000 Americans died from opioid overdoses, and the number of inpatient stays and emergency visits to hospitals related to opiods increased dramatically compared to previous years. The National Institutes of Health (NIH) have partnered with the Healthcare Cost and Utilization Project (HCUP) to gather data on opioid-related deaths and hospitalizations. These data include information about inpatient stays, emergency department visits, age, sex, income, and opiod-related use. For a given patient admitted to a hopsital for an opioid-related event, identify which of these events are disjoint. a)The patient was wealthy, and their income was in excess of $1,000,000.

b)The patient was 34 years old.

c)The patient was admitted to a small hospital.

d)The patient was female.

f)The patient earned $50,000 yearly.
