Answer: The probability of 1 particular person always being included is 1. (i.e., he is always included and never excluded)

Step-by-step explanation:

Out of 12 persons, groups of 4 persons are formed.

Which implies there are 3 groups where all the 12 persons are equally divided into[as 12 is perfectly divisible by 4, 12/4=3 ]
