What is the missing number?

A woman in Atlantic City was losing at the roulette wheel. When she was down to her last 10 dollars, she asked the fellow next to her for a good number. “Why don’t you play your age?” he suggested. The woman agreed, and then put her money on the table.
The next thing the guy with the advice knew, the woman had fainted and fallen to the floor. He rushed right over. “Did she win?” he asked. “No” replied the attendant. “She put 10 dollars on 33 and 46 came in.”
