# Statistics - Probability

Viruses reach networks by requests for communication that are identified as packets. A security system can detect them if at least one such packet is observed by a network sensor. Assume that the probability of observing a single packet sent from a new virus is .001. The virus actually sends 150 packets to the network computer.
What is the probability that the virus is detected by the sensor?

I feel like the answer is .001 * 150 but I am not exactly sure.
