A student has five motor vehicle accidents in one year and claims that having five accidents is not unusual. Use the frequency distribution below to determine if the student is correct.

P(5 or more accidents) = (45)/( total ) = 45/(260 + 500 + 425 + 305 + 175 + 45) = 0.0263

Since this tail probability is less than 0.05 (general thumb of rule), this event is unusual
