Answer 2

Answer:

23/49

Step-by-step explanation:

Information :

➡A deck of cards has 52 cards.

➡26 are red cards and 26 are black cards.

➡Black cards include 13 spades and 13 clubs

➡Black cards include 13 hearts and 13 diamonds.

QUESTION :

Total no. cards = 52

3 cards of spades are lost,

Therefore,

Remaining no. of cards = 49

Remaining no. of cards = 49No. of remaining black cards = 26 - 3 = 23

{ => Spades are black cards}

{ => Black cards are 26 in numbers , i.e, half of total cards }

Now,

Probability of getting a black card =

Probability of getting a black card ==> No. of observations/No. of total outcomes

=> No. of black cards/ No. of cards

=> 23/49

ANS) 23/49
