Please Help!

The prime numbers greater than 10 and less than 20 are 11, 13, 17, and 19. The product of any two of these primes is less than 400.

Let’s list the possible products:

11 * 13 = 143

11 * 17 = 187

11 * 19 = 209

13 * 17 = 221

13 * 19 = 247

17 * 19 = 323

So, there are 6 different products that Syd could have ended up with. Please note that 210 is not a product of two prime numbers greater than 10, which is why it was incorrect. I hope this helps! 😊
