Assuming that packet transmissions and retransmission can both be described as a Poisson process, calculate the probability that a data packet transmission in an S-ALOHA system will experience a collision with another user. Assume the total traffic rate λt = 10 packets/sec and the packet duration τ = 10 msec.
