The distribution depends on what the variable is.
If the key outcome is the number on the top of the die, the
distribution in multinomial (6-valued), not binomial.
If the key outcome is the number of primes, composite or
neither, the distribution is trinomial.
If the key outcome is the number of sixes, the distribution is
binomial with unequal probabilities of success and failure.
If the key outcome is odd or even the distribution is binomial
with equal probabilities for the two outcomes.
Thus, depending on the outcome of interest the distribution may
or may not be binomial and, even when it is binomial, it can have
different parameters and therefore different shapes.
