why do you multiply by lambda why do we multiply by lambda why do we add a lambda to exponential distribution why do we multiply lambda why is lambda used in exponential distribution why do you do a lambda why do we multiply lambda in exponential distribution which functions are lambda and how do we do this in exponential distributions why do we use lambda for exponential distribution why do we multiply by lambda exponential distribution why use lambda why do we multiply by lambda exponential distribution why do we multiply by lambda why multiply by lambda why do you use lambda in exponential distribution? why do we multiply by lambda why do we multiply by lambda exponential distribution why lambda in exponential distribution why do we multiply by lambda exponential distribution? when do we divide by lambda
