I summed the open interest (number of contracts outstanding) for out-of-the-moneys and divided by the sum of open interest for in-the-moneys.

Due to the $ decay factor, the ratio of the initial $ invested in, say calls, to the ratio of final $ value of the contracts at experation is very likely worse than going by the final ratio of contracts outstanding at expiration.

So while the number of contracts that expire worthless is likely far less than 90%, the number of contracts which lose money should be closer.
