Web15 jul. 2024 · Thus the probability that a prime is selected at random is 15/50 = 30%. This process can be carried out by simply counting primes as long as we have a list of primes. For example, there are 25 primes less than or equal to 100. (Thus the probability that a randomly chosen number from 1 to 100 is prime is 25/100 = 25%.) Web7 aug. 2014 · Combinatorial prime count methods. These include the Legendre, Meissel, Lehmer, LMO, and LMO extensions. See code for each at primecount or Math::Prime::Util. These are much, much faster than sieving. A single core can count in a second what primesieve (the current fastest sieve code) takes over 2 hours to do using 8 cores.
