I think this is correct. The probability would be 4!/4^4.

6/4^3 = 0.09
Can someone explain?

This is what I personally feel

Good event = all 4 people getting same number. can be 4 possibilities

Total events = 4*4*4

P= 4/4*4*4 = 1/16

4! / 4^4 = 4*3! / 4*4^3 = 3! / 4^3 = 6 / 4^3 = 0.09

1st chance choose out of 4
2nd out of 3
3rd out of 2
4th the remanining one

different selections = 4! = 24

total selections = 4*4*4*4 = 256

P(different selections) = 24/256 = 3/32
