You pick three cards from a deck without replacing a card before picking the next card. What is the probability that all three cards are kings?

Respuesta :

Probability that all three cards are kings
= (4/52) x (3/51) x (2/50)
= 1/5525

Probability that all the three cards are of king without replacing a card is equals to [tex]\frac{1}{5525}[/tex].

What is probability?

" Probability is defined as the ratio of number of favourable outcomes to the total number of outcomes."

Formula used

Probability = [tex]\frac{Number of favourable outcomes}{Total number of outcomes}[/tex]

According to the question,

Total number of cards = 52

Condition given to choose a card is without replacing

Total number of king cards = 4

Probability of choosing first king card 'P(A) ' = [tex]\frac{4}{52}[/tex]

Probability of choosing second king card ' P(B)' = [tex]\frac{3}{52}[/tex]

Probability of choosing third king card 'P(C)'= [tex]\frac{2}{52}[/tex]

Probability that all the three cards are of king without replacing a card

= P(A) × P(B) × P(C)

= [tex]\frac{4}{52}[/tex] ×[tex]\frac{3}{52}[/tex] ×[tex]\frac{2}{52}[/tex]

= [tex]\frac{1}{5525}[/tex]

Hence, probability that all the three cards are of king without replacing a card is equals to [tex]\frac{1}{5525}[/tex].
