Answer:
The probability that the card drawn is a club is 0.25.
The probability that card drawn is a club, when it is given that the card is black is 0.5.
Explanation:
In a standard deck of cards:
Total number of cards = 52
Total number of cards of each suit (club, spade,heart, diamond) = 13
The probability that the card drawn is a club is


Therefore the probability that the card drawn is a club is 0.25.
Let A and B represents the following events:
A : Card is black
B : Card is a club
Total number of black cards = 26

From the above parts

Total number of black club cards = 13

We need to find the probability that card drawn is a club, when it is given that the card is black.


Therefore the probability that card drawn is a club, when it is given that the card is black is 0.5.
