There are $n$ stations in slotted LAN. Each station attempts to transmit with a probability $p$ in each time slot. What is the probability that ONLY one station transmits in a given time slot?

There are "n" stations in LAN. According to question, only one station want to transmit , in the sense among "n" stations, "n-1" should not be allowed to transmit the data when one station is already is tranmitting the data.

In our question suppose "n" leveled station is transmitting the data with probability "p" then remaining '"n-1" should not be allowed to transmit the data at given slot.
