| 2013-01-16 14:54:10 +0200 | asked a question | sage sample hi i have a problem to solve, sorry if my english is bad :D: I have to calculate function pi(x) that gives me a number of prime-numbers in range from zero to x. x=10^10 and i have to take a sample of n random numbers from 1 to x and test how much of them are primes. then from that part(proportion) i have to calculate pi(x). another question is : what amount of sample i have to take so that relative error, when i calculate number od prime number by prime_pi(10^10), falls below 1%. if you have any question just ask and I will try to answer them. thank you soo much :D :D :D |
