From that result, you want to additionally filter out who didn't get the second advertisement. Since that information is contained

Sorry, I had an extra '9' in there. Math is actually:
54 * 69 * 1 * 65 * 1 * 2 * 1 * 65 * 1 * 24 = 755632800
Still a lot of operations, and if you index the state field, you can
