355/113 is the best fractional approximation of pi with less than 5 digits on both numerator and denominator, with 6 decimal digits of precision. It is constructed by taking the sequence of the first 3 odd numbers, each repeated exactly once, as such: "113355", then splitting the resulting string in halves, taking the first half as denominator, and the second as numerator.
A 4-set venn diagram can't be constructed with circles because it wouldn't show exclusive intersections between opposed sets.
A talks to B, B talks to C; A is married, C is not married. Therefore, a married person is talking to a non-married person.
for the third one because it stumped me a bit, there are 2 posibilites:
- Am -> Bu -> Cu
- Am -> Bm -> Cu
Either way there is a married person talking to a non-married person.
You must be fun at parties 😄
