Q1. A network has a packet loss rate of 5%. How many packets need to be sent to ensure that at least one packet is received?
Answer: 20
Explanation: Using the formula for expected number of transmissions = 1 / (1 - loss rate) = 1 / 0.95 = 1.0526, for 20 packets, probability of at least one success = 1 - (0.05)²0, practically 20 is a safe number.
