rectangular garden measures 40 ft by 30 ft. It is bordered and surrounded by a path measuring 3 feet wide. What is the area of the path? Draw a picture showing a 3 foot wide path surrounding the original dimensions of the garden. Calculate the area of the expanded garden and subtract the area of the original garden. The difference will be the area of the path. The path has an area of _____ square feet.
Continuous Probability Distributions
Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.
Normal Distribution
Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!
