Question

A card is drawn at random from a well shuffled pack of playing cards. find the probability that it is a spade or a king.

Answer 1

A deck of cards contain 52 cards
that is 4 sets. each set contains 13 cards
like that there are 4 type of cards. 1st set is hearts, 2nd set is diamonds, 3rd set is clubs and 4th set is spades

Now let's find the probability for a spade card

no. of spades in deck = 13
total no. of cards( deck ) = 52

p (s) = 13/52 = 1/4
therefore 1/4 is the probability of getting a spade card among the whole deck of cards.

Now let's find the probability for a king card in whole deck

*each set contain 1 king card. so, as there are 4 sets 4 kings will be there.

No. of King cards in whole deck = 4
No. of total cards = 52

p (k) = 4/52 = 1/13

therefore 1/13 is the probability of King card.

So friend, like this you can find any probability by following this small method.
