Yeah ! The answer is 2/5525 But i need to know how these kind of problems are solved

of well the fact is your chance of the first card being a king is 1/52

ChrisVBest ResponseYou've already chosen the best response.1
the second card being a king would be 1/51

ChrisVBest ResponseYou've already chosen the best response.1
and the third card being an ace would be 1/50

how they came up with that answer i do not know

ChrisVBest ResponseYou've already chosen the best response.1
unless they are somehow figuring in that there are 4 of each

Oh Ok there are 4kings So chance of the first card being a king is 4/52

So multiply and its 2/5525

But Btw do you know Why we are multiplying ?

ChrisVBest ResponseYou've already chosen the best response.1
well to find the probability of something happening you have to multiply the number of times it could possibly occure then divide it by the total number of possibilities

like if you have 10 books and 2 are school books

ChrisVBest ResponseYou've already chosen the best response.1
whats the probability that the first book you pull out of your bag would be a school book

StArAnGeLBest ResponseYou've already chosen the best response.0
yes But we didnt multiply anything here ?

ChrisVBest ResponseYou've already chosen the best response.1
so say you have taken 1 school book out already

ChrisVBest ResponseYou've already chosen the best response.1
whats the chance of pulling both school book out of the bag in a row

ChrisVBest ResponseYou've already chosen the best response.1
well we already know the first one was 2/10
 2 years ago

ChrisVBest ResponseYou've already chosen the best response.1
so you multiply 2/10 x 1/9

ChrisVBest ResponseYou've already chosen the best response.1
the probability of pulling them both out in order would be 2/90 or 1/45
 2 years ago

ChrisVBest ResponseYou've already chosen the best response.1
so out of every 90 times you try it, the probability of succedding is 2 times

OH Ohkay Thanks a lot =)

FoolForMathBest ResponseYou've already chosen the best response.1
we are multiplying because these are independent events. \( P(A\cap B)=P(A) \times P(B) \)

Disclaimer: I know this problem has been solved. I am just practicing here.  4 kings, want 2 4 aces, want 1 no replacement 52 cards in deck P(K) = 4/52. The 52count drops to 51 with no replacement. King count drops to 3 P(2ndK) = 3/51. The 51 card count drops to 50. King count drops to 2. Ace count remains at 4. P(Ace) = 4 / 50 Using the Multiplication Principle, the probability of these 3 events happening is (4/52) (3/51) (4/ 50) = 2/5525 . Multiplication Principle states: If an event occurs in m ways and another event occurs independently in n ways, then the two events can occur in m × n ways.
