The federal government has enacted maximum allowable standards for air pollutants such as ozone. Let X be the number of days per year that the level of air pollution exceeds the standard in a certain city. The probability distribution of X is given by

x	0	1	2	2	3
P(x)	0.33	0.38	0.19	0.06	0.04

Find the probability that the standard is exceeded on at least one day. Write only a number as your answer. Round to two decimal places (for example: 0.53). Do not write as a percentage.
