The life, in years, of a certain type of electrical switch has an exponential distribution with an average life β = 2. if 100 of these switches are installed in dif- ferent systems, what is the probability that at most 30 fail during the first year?

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
