4. A fire detection device uses 3 temperature-sensitive cells acting independently of each other in such a manner that any one or more may actuate the alarm. Each cell possesses a probability of 0.8 of activating the alarm when the temperature reaches 100°C or more. Find the probability that the alarm will function when the temperature reaches 100°C or more.
