  In this paper we report our systematic calculations of angular momentum $I$
ground state probabilities ($P(I)$) of boson systems with spin $l$ in the
presence of random two-body interactions. It is found that the P(0) dominance
is usually not true for a system with an odd number of bosons, while it is
valid for an even number of bosons, which indicates that the P(0) dominance is
partly connected to the even number of identical particles. It is also noticed
that the $P(I_{max})$'s of bosons with spin $l$ do not follow the 1/N ($N=l+1$,
referring to the number of independent two-body matrix elements) relation. The
properties of the $P(I)$'s obtained in boson systems with spin $l$ are
discussed.
