Answer:
The probabilitiy of pulling a seven is 1/13 or 7.69%
Step-by-step explanation:
Im not sure if you wanted just the probability of pulling a seven or if you wanted others as well but to find out the probability you take the total amount of cards, 52, then you take the total amount of 7's in the deck which is 4, one for each card type.
Therefore you get 4/52 or simplified to 1/13 by dividing by 4 on the numerator and the denominator.
