Answer: P = 4/52 = 0.077 or 7.7%
Step-by-step explanation:
I will answer in English.
We have a deck of 52 cards, and we want to find the probability of drawing, at random, a 1.
We have 4 1's in the deck, one for spades, one for hearts, one for diamonds and one for clovers.
So the probability can be calculated as the quotient between the total number of 1's in the deck and the total number of cards in the deck, this is:
P = 4/52 = 0.077
