government has devoted considerable funding to
missile defense research over the past 20 years.
The latest development is the Space-Based
Infrared System (SBIRS), which uses satellite
imagery to detect and track missiles. The
probability that an intruding object (e.g., a
missile) will be detected on a flight track by
SBIRS is 0.6. Consider a sample of 10 simulated
tracks, each with an intruding object. Let x
equal the number of these tracks where SBIRS
