Consider the population that consists of all soft contact lenses made by a particular manufacturer and define the random variable x=thickness. Erich that the total area under the density curve is equal to 1. The area of a triangle is equal to 1/2 base height. What is the probability that x is less than 0.20? What is the probability that c is less than 0.14? What is the probability that x is less than 0.26? What is the probability that x is between 0.14 and 0.20?
