... A popular gambling game called craps is described below. A player rolls two dice, and the sum of the two numbers that appear is recorded. If the sum on the first roll is 7 or 11, the player wins immediately and the game stops. If on the first attempt a sum of 2, or 3, or 12 is scored, the player los ...

... The variance is obtained simply through this data, suppose we have five persons with their haemoglobin level (g/dl) measurements (8, 9, 10, 11, 12). The mean value can be obtained simply by summation of all observations and divided by 5 (mean=x/n) =50/5=10 g/dl, then we are going to obtain the diff ...
