Answer:

C. [tex]\frac{1}{4}[/tex]

Step-by-step explanation:

Step 1: find the probability to satisfy the first roll

There are 3 odd numbers on the dice, so there's a 3/6 or 1/2 chance of rolling an odd number on the first roll.

Step 2: find the probability to satisfy the second roll

There are 3 even numbers on the dice, so there's a 3/6 or 1/2 chance of rolling an even number on the second roll.

Step 3: multiply the probabilities to get a compound inequality

[tex]\frac{1}{2} *\frac{1}{2} =\frac{1}{4}[/tex]

So... choice C? I suppose?
