Answer: 4.2%
Step-by-step explanation:
The deck has 52 cards, and a standard deck has 13 cards of each type, so there are 13 diamond cards.
Then the probability of drawing a random card that is a diamond card is equal to the number of diamonds card divided by the total number of cards:
p1 = 13/52 = 0.25
now, for the dice we have that the dice has 6 sides, but only one side has a 1, so the probability is;
p2 = 1/6 = 0.167
Now, the probability of both events happening at the same time, is equal to the product of both probabilities is:
P = p1*p2 = 0.25*0.167 = 0.042
So the probability is 0.042*100% = 4.2%
