The simplest rigorous proof of p 2 uses a versatile technique called the pigeonhole principle, which (in its simplest form) says that you can’t put m+1 envelopes into m pigeonholes without at least two of the envelopes ending up in the same pigeonhole. Perhaps the first written reference to the pigeonhole principle appears in 1622 in a short sentence of the latin work selectæ propositiones, by the french jesuit jean leurechon, where he wrote it is necessary that two men have the same number of hairs, écus, or other things, as each other.

By the pigeonhole principle, at least two must be of the same color another way of seeing this is by thinking sock by sock if the second sock matches the first, then we are done. The correct answer is $8$: first, as you said if we choose $6$ socks we will have at least one pair in fact we know something stronger, if we choose $7$ socks we either have $2$ pairs, or we have exactly $1$ pair and $1$ sock from each other color or $1$ pair and $3$ socks of the original color (just like mentioned above). Briefly, the pigeonhole principle says that, for sets x and y, if #x #y and f is a function from x to y, then f is non-injective some more curious inferences .

He took the beginning or first principle to be an endless, unlimited primordial mass (ἄπειρον, apeiron) the second view is found in a clearer form by . By the pigeonhole principle, which states that no function whose codomain is smaller than its domain can be injective, we can conclude that f cannot be injective this is a contradiction with the assumption that f is bijective. First form: the principle of sufficient reason of becoming (principium rationis sufficientis fiendi) appears as the law of causality in the understanding  second form: the principle of sufficient reason of knowing (principium rationis sufficientis cognoscendi) asserts that if a judgment is to express a piece of knowledge, it must have a .
As nouns the difference between principle and philosophy is that principle is a fundamental assumption while philosophy is (uncountable|originally) the love of wisdom as verbs the difference between principle and philosophy.

From this we have n(b) = 200 for n(a b) every third integer is a multiple of 3 which is 66 n(aub) = n(a) + n(b) we need to determine the number of multiples of 15 from 1 through 1000 each multiple of 15 is of the form 15r for some integer r from 1 through 66 using the inclusion/exclusion principle. Demonstrating what the pigeonhole principle is was that of the pigeons (go figure) in this example, there are 3 pigeonholes and 4 pigeons each pigeon is assigned a hole, and by doing that, at least two pigeons will have to share the same pigeonhole.
