With a standard deck of cards with 4 suites and 13 ranks:
A: what is the probability that a randomly drawn card is an ace or a heart?
B: Are the events Ace and Heart independent? What about the ace of hearts? Show the calculation to explain why or why not
(A)
P(Ace) = 4/52 = 0.0769
P(Heart) = 13/52 = 0.25
P(Ace & Heart) = 1/52 = 0.0192
So,
By Addition Theorem:
P(Ace OR Heart) = P(Ace) + P(Heart) - P(Ace & Heart)
= 0.0769 + 0.25 - 0.0192 = 0.3077
So,
Answer is:
0.3077
(B)
P(Ace) = 0.0769
P(Heart) = 0.25
P(Ace & Heart)= 0.0192
P(Ace) X P(Heart) = 0.0769 X 0.25 = 0.0192
Since P(Ace & Heart) = P(Ace) X P(Heart), the events Ace and Heart are independent.

Prisha has a standard deck of 52 playing cards. The deck contains 4 suits (hearts, diamonds, clubs, and spades), and each suit contains 13 cards labeled 2 through 10, as well as jack, queen, king, and ace. Four friends are trying to determine some probabilities related to drawing cards from the deck. Two cards will be randomly drawn from the deck, and after the first card is drawn, it is not replaced before the second card is drawn. Consider the...
The following question involves a standard deck of 52 playing cards. In such a deck of cards there are four suits of 13 cards each. The four suits are: hearts, diamonds, clubs, and spades. The 26 cards included in hearts and diamonds are red. The 26 cards included in clubs and spades are black. The 13 cards in each suit are: 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King, and Ace. This means there are four...
1. A standard deck of cards has 52 cards with 4 suits that include 13 clubs, 13 diamonds, 13 hearts, and 13 spades. Each suit includes an ace, a king, a queen, and a jack, and numbers 2 through 10. Assume that I choose one card from the deck. a. What is the probability that the card is either a queen or a 4? b. What is the probability that the card is not a queen and it is not...
Before each draw the deck is well shuffled and a single card randomly drawn. (Use 4 decimals for all answers) A. What is the probability that the first card drawn is a face card (a Jack, a Queen, or a King)? B. What is the probability that the second card drawn is red? C. What is the probability that the first card drawn is a face-card AND the second card drawn is red? D. What is the probability that the...
3. You have a standard deck of 52 playing cards. There are two colors (black and red) and four suits (spades are black, clubs are black, hearts are red, and diamonds are red). Each suit has 13 cards, in which there is an ace, numbered cards from 2 to 10, and three face cards (jack, queen, and king) a. You randomly draw and then replace a card. What's the probability it's an ace? What's the probability it's the 4 of...

4 cards are randomly drawn from a standard deck of playing cards. What is the prob- ability that all their suits are different? Hint: There are 52 cards in a standard deck of playing cards. A card can have 4 different suits: diamond ( ♦ ), club ( ♣ ), heart ( ♥ ), or spades ( ♠ ). There are 13 cards of each suit. Cards are further labeled by their rank: numbers 1 to 10 and three face...
Consider a standard deck of 52 cards with 4 suits. Define events! a. Suppose you pick 1 card at random from the deck. What is the probability that card is a heart? b. Suppose you pick one card from the deck. What is the probability that card is a 5? c. Suppose you pick one card from the deck. What is the probability that the card is a heart and a 5? d. Suppose you pick one card from the...
2. Consider a standard 52 card deck of playing cards. In total there are four cards that are Aces, four cards that are Kings, four cards that are Queens and four cards that are Jacks. The remaining 36 cards are four each of the numbers 2, 310. That is there are four cards that are twos, four cards that are threes etc. For this question, suppose that we reduce the number of cards in the deck by removing one of...
A deck of cards has 4 suits and 13 denominators. A full deck contains 52 cards A single card has three characteristics: suit, denomination and colour, for example a king of red hearts.
