Can anyone tell me how to work out the following:

A shuffled pack of 52 normal playing cards, each card is dealt face up in order, how long (on average) do you have to wait before (say) the Ace of Clubs is dealt?

Of course it is less than or equal to 52 because it has to come up, but how long on average?

Thanks

Also if anyone knows any good books that deal with such question s (and others that I have asked) I would be grateful for a recommendation!

Is there anyone here that knows how it feels to go up in space?

Is there anyone that know how it feels to go in space. Like, how does it feel when you are on the rocket and being blasted up? Is it a good feeling? And when you get to the moon, where does your oxygen come from? Can you run out? What will happen if you do? How do you get back home? Is it worth it being an astronaut?

(You don't have to answer all the questions, just one or two)

question about continuous functions?

we would like the function g(x)= square root of ( 16 - x^2 / 4 - x)
-4 < or = x < or = 4

to be continuous over the interval (-4,4). The value that would have to be assigned to g(4) to accomplish this is:
a) 0 b) 2 c) 2 * sqrt 2 d) 4 e) 4 * sqrt 2

and why.

thank you soooooo much
