Question
Suppose that a satellite defense system is established in which four satellites acting independently have a 0.9 probability of detecting an incoming ballistic missile. What is the probability that at least one of the four satellites detects an incoming ballistic missile? Would you feel safe with such a system?
Step 1
9$. This means that the probability of each satellite not detecting an incoming ballistic missile is $P(E^C) = 1 - P(E) = 0.1$. Show more…

A satellite defense system works by having four satellites act independently of one another. Each satellite has a 90% chance of detecting a missile. What is the probability the system detects an incoming missile? 99.99% 99% 10% 90%
A missile protection system consists of $n$ radar sets operating independently, each with a probability of .9 of detecting a missile entering a zone that is covered by all of the units. a. If $n=5$ and a missile enters the zone, what is the probability that exactly four sets detect the missile? At least one set? b. How large must $n$ be if we require that the probability of detecting a missile that enters the zone be $.999 ?$
Discrete Random Variables and Their Probability Distributions
The Binomial Probability Distribution
Homeland Security and missile defense technology make it paramount that we be able to detect incoming projectiles or missiles. To make the defense successful, multiple radar screens are: required. Suppose it is determined that three independent screens are to be operated and the probability that any one screen will detect an incoming missile is 0.8. Obviously, if no screens detect an incoming projectile, the system is unworthy and must be improved. (a) What is the probability that an incoming missile will not be detected by any of the three screens? (b) What is the probability that the missile will be detected by only one screen? (e:) What is the probability that it. will be detected by at least two out of three screens?
