hey smart guys help a dumbo like me please here's the problem:
there is a 3 digit code. 1 of the digits is the letter "M", but we don't know which spot in the code it takes. another digit is a letter, out of 18 possible letters (vowels and a couple others are omitted). again we don't know the position of this digit, but we know for sure that aside from the "M", there is another letter digit. finally, the third digit is a number. there are only 7 numbers it could be (some are omitted). and yes, we don't know which position the number is in either.
so the problem? how many possible combinations (or is it permuations? i'm not sure) are there for this criteria? i have nothing but my thanks to give to the brainiac who solves this

What are the actual, proven, mental and physical health benefits of meditation?
Not guided meditation, not transcendental meditation or anything like that. Just sitting down and being completely silent for ten to thirty minutes, twice a day, every day.
