Okay, I'm on a quiz bowl team and we have questions like this all of the time. No one on my team knows how to do them. We only have ten seconds to get the answer so we can't go 21+22+23+24...+40. So, I figure there must be some shortcut to figuring this out. Thanks in advance!

the conditional probability that all four flips will be heads. Then calculate the conditional probability of flipping four heads, given that the first two flips were heads. Now assign a random variable x, where the value of x is equal to the number of heads observed in the flips. Describe the probability distribution of x, and calculate the probability of observing three heads in four coin flips. (I don't even know where to start on this so if any statistics buffs could help me out I would really appreciate it)

When it comes to very large numbers, what does excel round the number at?
(e.g. for very small numbers, it is rounded down to zero).

For instance, when calculating the function (1+1/n)^n for increasing values of n, i get 2.718281 for a while but at one point and beyond it, I get 1.

What givessss?!

1. S is a nonempty subset of R that is bounded from above but has no greatest element (max). prove supS is a cluster point of S

2. Prove that a subset of a metric space is closed iff it contains all its cluster points.
