What is 5! ?
5!=120

1/120= 0.0083

but the options are

0.1
0.054
0.0167
Impossible to determine

Am I missing something?
You are missing the fact that they could be ordered according to increasing or according to decreasing age.
Each would be ordered by age.

so prob = 2/120 = 1/60 = appr .0167
Ah okay. Thanks!
