Evidently the quesiton is incomplete.

It is logic that the actions are roll a die and draw a card.

The two events are indepent, so the combined probability is the sum of the individual probabiliites.

Probability = number of positive events / number of possible events

Probability of rolling an even number = number of faces with even numbers / total number of numbers.

Probability of rolling an even number = 3 / 6 = 1/2

Probability of drawing an ace = number of aces in the deck of cards / number of cards

Probability of drawing an ace = 4 / 52 = 1 / 13

Combined probability = 1/2 + 1/13 = (13 + 2) / 26 = 15 / 26

Answer: option D. 15 / 26
