I_need_a_700plus Wrote:So if we start with statement 2: "there are a total of p prime numbers between 1 and 3,912" and we decided to list all the prime numbers: 2, 3, 5, 7, 11, 13, etc.. we will get let's say 3,000 prime numbers from 1 to 3,912 (I am just using 3,000 as an example given I did not list every prime #).
This is exactly the right reasoning.
If this was the case, then statement 2 will give us the the number / how many primes there are between 1 and 3,912. However, I thought we needed to determine the actual prime number. If so, then this would be insufficient.
I'd suggest that you should go back to the basic DS chapters and review what "sufficient" and "not sufficient" mean.
The thing in bold red is the exact definition of "sufficient" -- like, literally, that's how "sufficient" is defined -- but you're somehow coming out of this thinking the opposite. That means the base concepts here aren't in place. Go back and review them until they're like breathing.
