The given distribution table is, let us represent the blood owners as eggs and their values are given as 0, 1, 2, 3, 4, 5 and 6.
00:17
And their percentage are given as 30, 25, 25, 10, 5, 3 and 2.
00:31
And to convert them in probability, which is p of x, the percentage value is divided by 100.
00:38
Thus for the respective x values, their probabilities are 0 .30, 0 .25, 0 .25 .0 .5.
00:47
0 .25, 0 .10, 0 .05, 0 .03, and 0 .02.
00:57
And to find the standard deviation, first, the mean is calculated, which is summation xx into p of xi, which is calculated as 0 into 0 .30 plus 1 into 0 .25 plus 1 .5 plus so on up to 6 into 0 .02...
