Adrian can put a total of 1716 combinations in the player.
The formula to be used is as follows:
total combinations = n!/[r! *(n-r)!]
n = number of disks available = 13
r = number of disks that be held = 6
= 13! = (13• 12•11•10•9•8•7•6•5•4•3•2•1)/(6! <span>• 7!)
</span>=1716
Thank you for posting your question. Feel free to ask me more.
It would be an open circle with an arrow going to the right
2.1 x 10^10/ 7 x 10^17
= 3 x 10^-8
hope this helps and have a great day :)
