Eight cards are selected with replacement from a standard pack of 52 playing cards, with 12 picture cards, 20 odd cards, and 20 even cards.
How many different sequences of eight cards are possible?
Hello, struck!
Eight cards are selected with replacement from a standard decl of cards.
How many different sequences of eight cards are possible?
For each of the eight cards, there are 52 possible choices.
Answer: .$\displaystyle 52^8 \:=\:5,345972853 \times 10^{13}$
Ok so that makes it a permutation problem of type 'with replacement' instead of a combination problem?
A related question has got me stuck again.
(b) How many of the sequences in part (a) will contain three picture cards, three odd-numbered cards and two even-numbered cards.
Note: (a) was the original question, i.e., "How many different sequences of eight cards are possible?"
I do really have a trouble with permutations and combinations, so a little explanation in this answer will be greatly appreciated.
So points that I have noticed: (please correct if mistaken)
* There are 3 types of objects
* There are 8 objects to be selected out of the 3 types
