Question 121285: from a homework handout it reads, for each natural numbers,n, let P(n)=the number of prime numbers less than n. P(1)=0,P(2)=0,P(3)=1,P(4)=2,P(5)=2,P(6)=3. I have the domain as 1,2,3,4,5,6 and the range as 0,0,1,2,2,3 but what is P(20)? i can't get the answer.i think it is 8 but i think i'm wrong

The first 8 primes are 2, 3, 5, 7, 11, 13, 17, and 19, all less than 20. Yes, your answer is correct.
