For Hamilton to be champion at the Mexican GP, the following permutations apply:

If Hamilton takes victory (25pts) and fastest lap (1pt), he will be champion if Bottas finishes fourth (12pts) or lower
If Hamilton takes victory without the fastest lap, he will be champion if Bottas finishes fifth (10pts) or lower
If Hamilton finishes second (18pts) with the fastest lap (1pt), he will be champion if Bottas finishes eighth (4pts) or lower
If Hamilton finishes second without the fastest lap, he will be champion if Bottas finishes eighth, without the fastest lap, or lower.
If Hamilton finishes third (15pts) with the fastest lap (1pt), he will be champion if Bottas finishes ninth (2pts) or lower
If Hamilton finishes third without the fastest lap, he will be champion if Bottas finishes 10th or lower without the fastest lap
But...

If Hamilton finishes fourth or lower, the title race definitely goes on to the United States GP next week.
