USA snapshot presented a bar graph depicting business travelers’ impression of wait times in airport security lines over the past 12 months. Statistics were derived from Travel Industry Association of American Business Traveler Survey of 2034 respondents. Is this a probability distribution?

Worse – 49%
Same 40%
Better – 11%

How do I do this problem??
