you only integrated with respect to fu(u). Now you have to integrate with respect to fv(v). Or you could have just used a double integral to start with...
Well the answer to a. is
P{ X < a } = e^(-גa)
= e^(-0.5)
= 0.6065
where ג = 0.5 <- the rate equals lamda
Since P{ X >= a } = 1 - ( 1 - e^( גa ) ) = e^(-גa)
right?
Poisson Distrobution-HELP! URGENT!
the problem:
The Breakdowns of a robot follow a Poisson Dist. with an avg of .5 breakdowns per 8-hour workday. If this robot is placed in service at the beginning of the day, find the probability that:
a. It will break down durring the day.
b. It will...
