An electrician disconnected 5 wires of different colors from their respective connections and forgot the order in which they wer e placed. Assuming you connect them by trying different sorts and that the last one is correct, how many tries must you do before getting it right?
1 answer:
Answer:
120 tries
Step-by-step explanation:
You can try 5 different wires in the first connection.
Then you have 4 wires left, so you try 4 wires in the second connection. Remember, you are now trying 4 wires for each of the first 5, so up to here you already made 4 * 5 tries = 20 tries.
Next you try 3, then 2, then you have 1 left.
Number of tries: 5 * 4 * 3 * 2 * 1 = 120
Answer: 120 tries
