The probability that a radar will detect an object in one cycle is p. The probability that the object will be detected in n cycles is

A radar complex consists of eight units that operate independently. The probability that a unit detects an incoming missile is 0.9 . Then the probability that an incoming missile will not be detected by any unit is

A radar complex consists of eight units that operate independently. The probability that a unit detects an incoming missile is 0.9. The probability that an incoming missile will not be detected by at most four units is

A radar complex consists of eight units that operate independently.The probability that a unit defects an incoming missile is 0.9.Find the probability that an incoming missile will (ii)be detected by atmost four units.
