**--sample space**

cards = 52

outcome

aces = 4

Divide possible outcomes with sample test

ace_probability = aces / cards

Print probability rounded to two decimal places

print(round(ace_probability, 2))

**Output:**

0.08

The probability of drawing an Ace from a standard deck is 0.08. To determine probability in percentage form, simply multiply by 100.

**-- Ace Probability Percent Code**

ace_probability_percent = ace_probability * 100

Print probability percent rounded to one decimal place

print(str(round(ace_probability_percent, 0)) + '%')

Output :

**8.0%**

The probability of drawing an Ace as a percent is 8%.

**---Create function that returns probability percent rounded to one decimal place**

def event_probability(event_outcomes, sample_space):

probability = (event_outcomes / sample_space)*100

return round(probability, 1)

Determine the probability of Drawing heart

hearts = 13

heart_probability = event_probability(hearts, cards)

Print each probability

print(str(heart_probability) + '%')

**Output:**

25.0%

**Determine the probability of drawing a face card**

face_cards = 12

face_card_probability = event_probability(face_cards, cards)

print(str(face_card_probability) + '%')

**Output:**

23.1%

**---Determine the probability of drawing the queen of hearts**

queen_of_hearts = 1

queen_of_hearts_probability = event_probability(queen_of_hearts, cards)

print(str(queen_of_hearts_probability) + '%')

**Output:**

1.9%

**---Sample Space**

cards = cards - cards_drawn

Determine the probability of drawing an Ace after drawing a King on the first draw

aces = 4

ace_probability1 = event_probability(aces, cards)

Determine the probability of drawing an Ace after drawing an Ace on the first draw

aces_drawn = 1

aces = aces - aces_drawn

ace_probability2 = event_probability(aces, cards)

Print each probability

-Drawing an ace, a king or a queen.

-Sample Space

cards = 52

Calculate the probability of drawing a heart or a club

hearts = 13

clubs = 13

heart_or_club = event_probability(hearts, cards) + event_probability(clubs, cards)

Calculate the probability of drawing an ace, king, or a queen

aces = 4

kings = 4

queens = 4

ace_king_or_queen = event_probability(aces, cards) + event_probability(kings, cards) + event_probability(queens, cards)
