Question

If a card is picked up at random from a pack of 52 cards. Find the probability that it is (i) a spade

Answer 1

Answer:

We know that A set of 52 card contains 13 types of cards in 4 categories

• Spade
• Heart
• Diamond
• Club

Then probability of getting a spade is 13/52.

Answer 2

Answer:

The probability that it will be a spade is 16/52

Step-by-step explanation:

Step 1:

Probability of event A(card being king) = 4/52

Probability of event B(card being spade) =13/52

Step 2:

As events A and B are dependent events (there is possibility of king of spade)

Step 3:

P (A  or B) = P ( A )  +P ( B) –P ( A and B)

Step 4:  

Result = 4 / 52 + 13 / 52 -1 / 52 = 16 / 52
