Question

What is the chance of picking a spade or an ace not of spade from a pack of 52 cards?

Answer 1

◆P(getting a spade)= No.of favourable outcomes/total no. of outcomes

=). 13/52 =) 1/4. [ since, there are 52 cards in a pack]


◆P(getting an ace not of spade)= 3/52

Answer 2

Answer:

We know that there are 52 cards in total.

Hence, the total number of possible outcomes is 52

Probability of drawing an ace or a spade or both from a deck of card is

The total number of spades in a deck of cards is 13

The probability of drawing spades in a deck of cards is P(A)=13/52

The total number of aces cards in a deck of cards is 4

The probability of drawing aces in a deck of cards is P(B)=4/52

The total number of aces of spade is 1

P(A∩B)=1/52

Probability of drawing an ace or a spade or both from a deck of card is

P(A∪B)=P(A)+P(B)−P(A∩B)

= 13/52+4/52−1/52

=16/52

=4/13

Probability of drawing an ace or a spade or both from a deck of cards is 4/13.
