If you roll a fair six-sided die 1000 times the die would come up even about 500 times. It will not be exactly 500 times, due to random probability, but it will be close. The more times you roll it, the ratio of even to odd will come closer and closer to the theoretical probability of 0.5.
If George rolls the die 300 times, how many fives will he roll?
With 1000 rolls of a die, and each number having a probability of 1/6, I would not expect any peaks.
The probability of rolling a four on a single roll of a fair die is 1/6. So the expected number of 4s in 450 rolls is 450*1/6 = 75.
A fair coin would be expected to land on heads 10 times on average.
A fair coin would be expected to land on heads 75 times.
You should be able to buy rolls from your local bank. At least, I would think so.

Assuming the length of aluminum foil roll is 10 meters and Jupiter's equatorial circumference is approximately 439,264 km, 1 mole of aluminum foil rolls (6.022 x 10^23 rolls) end to end would encircle Jupiter 2.46 x 10^20 times.
Assuming you mean each roll has 25 coins, 90 rolls would be $112.50.
i would think $80 to $200 depending on the condition they are in
You should think as many times as you would like.
No, not everyone has the money to buy a Rolls and there are not enough Rolls built for everyone to have one. ^If every body started to buy rolls royces (it's not going to happen), Rolls Royce motorcars would increase production to meet demand.
Assuming your measurements are correct, I would buy 10 rolls of underlayment = 1000 sf. (Most rolls of underlayment come in 100 ft rolls...but double check the rolls you are getting as there are a few that have other specs).
You should think as many times as you would like.
Of those three, Rolls-Royce would undoubtedly stand highest.
Oh, dude, negative infinity times negative infinity is technically positive infinity. It's like when you multiply two negatives, they cancel each other out and become positive. So yeah, in the wild world of math, that's how it rolls.
