Suppose that two cards are randomly selected from a standard?
52-card deck. (a) What is the probability that the first card is a
club and the second card is a club if the sampling is done without?
replacement? (b) What is the probability that the first card is a
club and the second card is a club if the sampling is done with?
replacement?

A card is randomly selected from a standard, 52-card deck. The
denomination on the card is recorded so that the resulting sample
space is {A, 2, 3, 4, 5, 6, 7, 8, 9, 10, K, Q, J}. (In other words,
we ignore the suits.) (a) (5 points) Given that the card selected
displays some number from 3 to 10 (inclusive), what is the
probability that the value on the card is not a multiple of 4? (b)
(5 points) Suppose...

A card is randomly drawn from a standard deck of 52 playing
cards. If event A is drawing a queen, and event
B is drawing a spade, find the following
probabilities. Express answers as a decimal to the nearest
thousandths.
(a) P(A and B)
(b) P(A or B)
(c) If a spade has been drawn from the deck, what is the
probability of drawing another spade?

Probabilities with a deck of cards. There are 52 cards in a
standard deck of cards. There are 4 suits (Clubs, Hearts, Diamonds,
and Spades) and there are 13 cards in each suit. Clubs/Spades are
black, Hearts/Diamonds are red. There are 12 face cards. Face cards
are those with a Jack (J), King (K), or Queen (Q) on them. For this
question, we will consider the Ace (A) card to be a number card
(i.e., number 1). Then for each...

We are drawing two cards without replacement from a standard
52-card deck. Find the probability that we draw at least one
red card.
The probability is
nothing.

A person draws 3 cards without replacement from a standard
52-card deck. Find the probability of drawing exactly two 4 , 5 ,6
, or 7s.

A person draws 3 cards without replacement from a standard
52-card deck. Find the probability of drawing exactly two 2, 3, 4,
or 5s.

Suppose 2 cards are drawn randomly for a standard 52 card
deck.
What is the probability that the second card is a face card (J,
Q, or K) when the two cards are drawn without replacement?
I'm stuck on this question, my hint was to draw a tree diagram
to calculate the probability.

Lacy draws a diamond from a standard deck of 52 cards. Without
replacing the first card, she then proceeds to draw a second card
and gets a club.
Are these events independent?
Input Yes or No:
Determine the probability of drawing a diamond and then a club
without replacement.
Write your answer in decimal form, rounded to four decimal places
as needed.
