Final answer:
The probability of drawing a 1 from a deck of cards is 0.0769, or 7.7% rounded to the nearest tenth.
Step-by-step explanation:
To find the probability of drawing a 1 from a deck of cards, we need to know the total number of cards and the number of 1 cards in the deck. Let's assume we have a standard deck of 52 cards. Out of these 52 cards, there are 4 1 cards (one for each suit). Therefore, the probability of drawing a 1 is:
P(1) = Number of 1 cards / Total number of cards = 4 / 52 = 0.0769
Rounded to the nearest tenth, the probability of drawing a 1 is 7.7%.
