Unformatted text preview: has this probability to do with the above?) The probability that the missile is not detected by any of n sets is given as (1 − 0.9)n = 0.1n . This event is the exact opposite of ”at least one of the sets detects the missile”. Therefore, we can compute the probability asked for as 1 − 0.1n . b) How large must n be if we require that the probability of detecting a missile that enters the zone be 0.999 ? 0.999999 ? 0.999 = 1 − 0.13 , 0.999999 = 1 − 0.16 In the first case we would need 3 radar sets, in the second 6. c) If n = 5 and a missile enters the zone, what...
