ROLL A DICE [2]

If you roll a stardard dice six times, then what is the probability that will roll 6 same surfaces? (e.g: 1-1-1-1-1-1)

AUTO ANSWER (AFTER SEVERAL DAYS):

The probability is: \(\dfrac{6}{6}.\dfrac{5}{6}.\dfrac{4}{6}.\dfrac{3}{6}.\dfrac{2}{6}.\dfrac{1}{6}\approx1,5\%\)

P/s: You always type incorrectly

Ex: Standand, not stardard

The probablity of rolling one first time is \(\dfrac{1}{6}\)

Six times that, we have: \(\left(\dfrac{1}{6}\right)^6\)=\(\dfrac{1}{46656}\)

But is this correct, because it is BEST IQ, right?
