Take one sheet out of your newspaper, and fold it in half, then fold it in half again, and again, and again. Can you fold it 30 times? Pretending that you can (you probably can’t fold it more than 8 times), how thick would it be after 30 times? Assume the paper is 1/200 cm. thick. Write a program to solve this puzzle. Prompt for the number of folds and output the thickness in meters using python

In class, we analyzed Buffon's needle experiment. We showed that if a large sheet of paper has parallel lines that are 1 inch apart, and we throw a needle of length 1/2 inch at it, the probability that the needle hits a line is l/r. We can estimate π by throwing many needles and seeing how many throws hit a line. Suppose we throw a needle n times, and each throw is independent. Let X be the number of throws...

The federal express parcel delivery company would like to estimate the average delivery times to places within Toronto. A random sample of letters are to be delivered and the number of days for each letter to arrive at its destination is recorded. The measurements are expected to have a standard deviation of 3 days. If the estimate of the mean delivery times is desired to be correct to within 0.5 day with confidence level equal to 0.95, how many letters...
