You can put this solution on YOUR website! You have to calculate the odds of not rolling a 6 and then subtract the result from 1.0.
The odds of you not rolling a 6 on a roll is 5/6 (the odds of rolling a 6 = 1/6)
You try again, 2nd try. Same as before:
The odds of you not rolling a 6 on a roll is 5/6
And again. Odds of rolling a six on a roll: 5/6
Once more. Odds of rolling a six on a roll: 5/
So you tried 4 times:
5/6 * 5/6 * 5/6 * 5/6 = 625/1296 ~= 0.482
Therefore, the odds of rolling a 6 within four rolls is 1 - 0.482 = 0.5177; 0.5177 x 100 = 51.77% are your odds of rolling a 6 in 4 tries, 52% if they are asking you to round the number.
