Hi Everyone,
below I've attached an embarrassing drawing of a circuit with switches. Signal enters from the left side at both line. Given that each switch has a 50% chance of being open, what is the probability of signal reaching the end of the circuit(far right)?
The answer that I got was 45/128 but I have a feeling its wrong.
Cheers.
