Solution to Question 1 Let us first write the sample space S of the experiment. S = {1,2,3,4,5,6} Let E be the event "an even number is obtained" and write it down. E = {2,4,6} We now use the formula of the classical probability.A is the correct answer. Remember, in order to calculate the median, you must first order the values in the sample from lowest to highest. Doing so yields: 110 116 124 132 168 This sample is of size 5, and odd number, so the middle value of 124 is the sample median. 5. C is the correct answer.Download Free PDF. Download Free PDF.
