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 work for at least 4 hours without breakdown
c. Does what happened the day before have any effect on your answers? why?
I'm a newb to probability and am I'm haveing trouble figuring out where to begin. I know that the rate(lamda) has something to do with the percent of break downs and the work day. Is it .5*workday or just .5. I just don't know where to begin with this problem.
