I believe it would depend upon the entropy used for the seed, as that would affect how many bits the checksum represents. https://github.com/bitcoin/bips/blob/master/bip-0039.mediawiki#Generating_the_mnemonic
So for a 24 word / 256 bit mnemonic the checksum is 8 bits, thus there are 8 valid checksums and if you picked a random checksum from the wordlist of 2048 words you'd have a 1 in 256 chance of picking a valid one.
