Mr Murphy needs some help!!!

Hi all,

I hope you are all having a good holiday!

I need some help!

My burglar alarm at home is causing me a problem. Four of the buttons aren’t working so I need a new 4 digit code.

The buttons that aren’t working are the 0, 4, 5 and the 7 so that leaves me with just the 1, 2, 3, 6, 8, 9.

Can you choose four numbers from the buttons available and tell me all the possible four digit codes I could choose from.
