Example 2. A three-digit number (that is, a number from 100-999) is selected "at ran- dom." ("At random" means that we assume all numbers to have the same proba- bility of being selected.) What is the probability that all three digits are the same? There are 900 three-digit numbers; 9 of them (namely 111, 222, . ., 999) have all three digits the same. Hence the desired probability is 0 = 10 ... %3D 900
