6. Red queens and black jacks are removed from a pack of 52 playing cards. A
card is drawn at random from the remaining cards, after reshuffling them,
Find the probability that the drawn card is
A queen
Answers
Answer:
2 red queens and 2 black jacks are removed from a pack of 52 cards.
So, cards remaining are 48.
∴n(S)=48
We need to find probability that 1 card drawn at random is
(1) a king
There are 4 kings in a pack.
Let A be the event of drawing a king.
∴n(A)=4
Therefore probability of drawing a king from 48 remaining cards is
P(A)=
n(S)
n(A)
P(A)=
48

(2) of red colour
After removing 2 red queens, there remain 24 red colour cards in a pack.
Let B be the event of drawing a red colour card from remaining 48 cards.
∴n(B)=24
Therefore probability of drawing a red colour card is
P(B)=
n(S)
n(B)
P(B)=
48

(3) a face card
2 red queen and 2 black jacks are removed from a pack. Therefore, total face cards remaining are 8.
Let C be the event of drawing a face card.
∴n(C)=8
Therefore probability of drawing a face card is
P(C)=
n(S)
n(C)
P(C)=
48
8

(4) a queen
There are remaining only 2 queens after removing 2 red queens.
Let D be the event of drawing a queen.
∴n(D)=2
Therefore probability of drawing a queen is
P(D)=
n(S)
n(D)
P(D)=
48

Step-by-step explanation:
Answer:
1/26
Step-by-step explanation:
There are a total of 2 red queens and 2 black queens in a deck. If the red ones are removed, you'll be left with 2 black queens.
Therefore the probability will be:- 2/52 = 1/26
