Assuming a "standard number cube" is a d6--a six-sided die used in craps, Monopoly, Trivial Pursuit, etc.--and it's fair:
P(nothing)=0. "Nothing" is a strange way to put it, but you can't get less than 1.
P(1)=1/6 or 16.7% or 0.1667.
P(odd) is P(1)+P(3)+P(5)=1/6+1/6+/16=3/6=1/2=0.5=50%
This is probably done by inspection of the probability space (write the numbers 1 to 6 on a piece of paper) and assumption of equiprobability of events (the die is fair). There's more complicated rules if, say, they want to know the probability you roll less than four or even (because you'd be counting "2" twice) that might show up elsewhere in this section of your textbook.
