The following question involves a standard deck of 52 playing cards. in such a deck of cards there are four suits of 13 cards each. the four suits are: hearts, diamonds, clubs, and spades. the 26 cards included in hearts and diamonds are red. the 26 cards included in clubs and spades are black. the 13 cards in each suit are: 2, 3, 4, 5, 6, 7, 8, 9, 10, jack, queen, king, and ace. this means there are four aces, four kings, four queens, four 10s, etc., down to four 2s in each deck.

you draw two cards from a standard deck of 52 cards without replacing the first one before drawing the second.

(a) are the outcomes on the two cards independent? why?

no. the events cannot occur together. yes. the events can occur together. no. the probability of drawing a specific second card depends on the identity of the first card. yes. the probability of drawing a specific second card is the same regardless of the identity of the first drawn card.

(b) find p(ace on 1st card and jack on 2nd). (enter your answer as a fraction.)
(c) find p(jack on 1st card and ace on 2nd). (enter your answer as a fraction.)
(d) find the probability of drawing an ace and a jack in either order. (enter your answer as a fraction.)

Step-by-step explanation:

Given that in such a deck of cards there are four suits of 13 cards each. The four suits are: hearts, diamonds, clubs, and spades. The 26 cards included in hearts and diamonds are red. The 26 cards included in clubs and spades are black. The 13 cards in each suit are: 2, 3, 4, 5, 6, 7, 8, 9, 10, Jack, Queen, King, and Ace. This means there are four Aces, four Kings, four Queens, four 10s, etc., down to four 2s in each deck.

When two cards are drawn without replacing the first one,

a) The outcomes cannot be independent.  Say for eg, first draw was an Ace, then next card being an ace changes to 3/51 thus drawing any card probability is not constant.  Hence the two events are not independent.

No. The probability of drawing a specific second card depends on the identity of the first card

b) Find P(ace on 1st card and jack on 2nd).

=

(c) Find P(jack on 1st card and ace on 2nd).

= This also would be the same because there are 4 jacks and 4 aces

=

(d) Find the probability of drawing an ace and a jack in either order. (Enter your answer as a fraction.)
