Explanation:
There are two possible sets of rolls:
Set 1:
Of the four people, three roll a 1 and one rolls a 3. The total ways to arrange these rolls among 4 people is
#(4!)/(3!*1!)=24/(6xx1)=4#
Set 2:
Of the four people, two roll a 1 and two roll a 2. The total ways to arrange these rolls among 4 people is
