In computer science, the count-distinct problem [1] (also known in applied mathematics as the cardinality estimation problem) is the problem of finding the number of distinct elements in a data stream with repeated elements. This is a well-known problem with numerous applications.
The probability of tossing tails is 1 − p (so here p is θ above). Suppose the outcome is 49 heads and 31 tails, and suppose the coin was taken from a box containing three coins: one which gives heads with probability p = 1 ⁄ 3, one which gives heads with probability p = 1 ⁄ 2 and another which gives heads with probability p = 2 ⁄ 3 ...
If all are 1, then either the element is in the set, or the bits have by chance been set to 1 during the insertion of other elements, resulting in a false positive. In a simple Bloom filter, there is no way to distinguish between the two cases, but more advanced techniques can address this problem.
Monty Python's Flying Circus: Between 1974 and 1980 (Live at the Hollywood Bowl was released in 1982, but was performed in 1980), the Pythons made three sketch-based stage shows, comprising mainly material from the original television series.

An early reference to counting sheep as a means of attaining sleep can be found in Illustrations of Political Economy by Harriet Martineau, from 1832: "It was a sight of monotony to behold one sheep after another follow the adventurous one, each in turn placing its fore-feet on the breach in the fence, bringing up its hind legs after it, looking around for an instant from the summit, and then ...
Analysis: This is the gathering of program information from the intermediate representation derived from the input; data-flow analysis is used to build use-define chains, together with dependence analysis, alias analysis, pointer analysis, escape analysis, etc. Accurate analysis is the basis for any compiler optimization.
