Answer:
Step-by-step explanation:
hello,
I understand that there are only 4 cards and then the player draw a card out of the 4 cards, replace it so the second draw is still out of the 4 cards
How many ways can you draw two cards?
as the first card is replaced, this is 4*4=16
so there is 16 possibles ways
hearts hearts
hearts clubs
hearts diamonds
hearts spades
clubs hearts
clubs clubs
clubs diamonds
clubs spades
diamonds hearts
diamonds clubs
diamonds diamonds
diamonds spades
spades hearts
spades clubs
spades diamonds
spades spades
out of these 16 ways, how many have same colour for both cards?
I assume that there are only two colours Red and Black, so we can have
only 8 ways so the first probability is 8/16 = 1/2
out of these 16 ways, how many are red ace first and black ace?
There are 4 ways so the probability is 4/16 = 1/4
hope this helps
Standard deck has aces in four colors
Player draws one from four so the probability of drawing any first card is 1/4 (in the first drawing)
We replace the card so in second drowing its the same
So the probability of drawing two card of one chosen color is 1/4*1/4, and we have four colors
The probability of drawing two card of the same color is:
1/4*1/4*4 = 1/4
There are 2 red aces and 2 black aces
(sorry for coments - not reading carefully)
So a probability of drawing red ace in first drawing is 2/4=1/2
a probability of drawing black ace in second drowing is the same ('cause we replace the one drawn first)
So the probability that a red ace is drawn first and then the black ace is:
