Answer:

#1/3# or #33 1/3%#

Explanation:

The odd prime numbers that could appear on a die roll are #3# and #5# (note that #1# is not considered a prime).

Since theer are #6# possible roll outcomes,
the probability of an odd prime is #2# out of #6# or #2/6=1/3#.
(Often probability is expressed as a percentage in which case #1/3=33 1/3%#)
