An astronomer as
the mount palomar
Observatory notes that during the Geminid
meteor shower, an average of 50 meters
appears each hour, with a variance of
9 meteors squared.
The Geminid meteor shower will occur next week.
@) If the astronomet waches the shower
for 4 hour, what is the pobability that
atleast 48 meteor per hour will appear?
(b) If the astronomer watches for
additional hour, will this probability rise or
fall? why?
