5 per cent of 20 is 1. So if the student makes a mistake of exactly 5 per cent then his measurements are 20 +/- 1 cm. That is, 19 or 21 cm.

5/100 × 20 = 1cm
20cm+1cm= 21cm
20cm-1cm=19cm
So the two possible measurements are 21cm and 19

A class has 8 students who are to be assigned seating by a lot What is the probability that the students will be arranged in order shortest to tallest assume that no two students are the same height?
first you have to keep in mind that probability is # of favorable outcomes/ # of possible outcomes. we already know (given that no two students are the same height) that there is only 1 possible way to order the students from shortest to tallest therefore, we have established that we have 1/# of possible outcomes. to find the number of possible outcomes you take 8 factorial. 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 40320. now you have the # of favorable over # of possible = 1/40320 = .0000248015873 = 2.48015873 E-5.
