Example 2-2 suggests multiplying the random number by 6 and taking the floor of it to give a number in the range 1-6. This has two problems, firstly, the number, after multiplication, can be 0 and the floor of 0 is 0; secondly, the odds of getting 6 are less than that of getting any other number as the number can be exactly 1,2,3,4 or 5 but never 6. The correct way is to multiply by 6, then take the floor of this number and add 1 - this will give equal probablity to the numbers 1 to 6. |
