There are 4 jacks and 13 clubs in a standard 52 card deck of playing cards what is the probability that a card picked at random from a standard deck of playing cards is a club or a jack

Respuesta :

the answer is 4/13 , hope this helped :)

Answer:

[tex]P(A\cup B)=\frac{4}{13}[/tex]

Step-by-step explanation:

Given:

Total number of cards = 52

Number of jacks = 4

Number of club cards = 13

Number of jacks and club cards = 1

Let event A represents the jack and event B represents the club card.

[tex]P(A)=\frac{4}{52}[/tex]

[tex]P(B)=\frac{13}{52}[/tex]

[tex]P(A\cap B)=\frac{1}{52}[/tex]

The formula for probability of union is

[tex]P(A\cup B)=P(A)+P(B)-P(A\cap B)[/tex]

[tex]P(A\cup B)=\frac{4}{52}+\frac{13}{52}-\frac{1}{52}[/tex]

[tex]P(A\cup B)=\frac{4+13-1}{52}[/tex]

[tex]P(A\cup B)=\frac{16}{52}[/tex]

[tex]P(A\cup B)=\frac{4}{13}[/tex]

Therefore, the probability of a jack or club card is [tex]\frac{4}{13}[/tex].
