Probabilities are always going to be less than or equal to 1.

So what needs to be done is to calculate the combination with repetition. I don't just mean that someone who picks power steering may also pick power brakes. I mean take all the options available for that year and calculate the different number of combinations. Then using the known quantities of each RPO (and standard items) calculate the probability of achieving your specific combination of options (or standard items).
Again, agreed.

This would be another method of finding out that the probability of two Corvettes of the same model year being absolutely identical in terms of options is pretty low, probably zero.

...the owner of a '75 L-82 4spd Z07 convertible, w/1800 original miles had written a letter to GM on Nov 12, 1975 and GM responded saying there was 366 L-82 convertibles made in '75. I have a copy of the original letter from GM.

I've always wondered if they got somebody to actually sit down and sift through the records of all 38,000 cars built in '75 to get that number, calculated it like is commonly done here by multiplying numbers, or just took a wild guess.

Thanks
Do you actually have one of these or are you just trying to stir up the hornets nest?

I have always thought that you were pretty consistent. Get your toque out; looks like -30*C (-22*F) on Wednesday evening.

They must have kept better records than we think, I guess. The Black Book, for example tells all the numbers of A/C, pwr windows, pwr brakes, number of automatic cars, M-21 or M-20 cars, etc. Even with the earlier solid axle they know how many '57 Fuelies were made, how many big brake cars were made '57-'62 and so forth. They must have had some kind of system that kept track???

A good point, since we've always heard the records were not available. If someone at GM could send a letter with an exact number, why can't that information be made available to all of us?

I had a hard time getting some commercial freezers within -5 F of that back in the day.

Holy smokes that brisk

Almost 60F here today

Individual options yes. They needed to plan on how many power boosters etc. to buy for next year's production so records were kept that showed individual totals.

I've heard from more than on GM exec. that combinations of options would be a very expensive and time consuming process to administer which in the end had no value to GM. Coming from a manufacturing industry where virtually no two units were identical, I can see the monumental task and without having any real justification, there's no way could anybody make a successful business case.

It would be easy enough to do today- even a smartphone could do it but no such technology existed in the 50s-60s-70s.

Brisk? Yes. The windchill will be -33*F tomorrow. I saw -50*F when I lived in the Yukon many moons ago. Heh, it's Canada. Strangely you get used to it. Even the block heater on my 2013 Cruze is programmed NOT to work until 0*F. I can't even find the plug but I am not worried about it. That car starts right up at these temps. Cute little grocery-getter.

I don't think so. He lives in the same geographic region as me. He knows the drill at these temps. We go through it each January/February. Pretty standard stuff.

I had to replace my natural gas home furnace in early November. It is 96% efficient with new system 636 pipes. Up to code. Works very well, although often quite too much with these temps.
