The probability that a permutation does not have any elements in their original position approaches one over this number.
The probability that a permutation does not have any elements in their original position approaches one over this number. The xth root of x has its largest value when x is this number. The sum of all reciprocal factorials is this number, which was discovered by Jacob Bernoulli while studying compound interest. One plus this number raised to the product of i and pi is equal to zero. This number raised to the power of x is its own derivative. For 10 points, name this transcendental number that is the base of the natural logarithm and is equal to approximately 2.718.
