"if a die is rolled four times, what is the probability it lands on 6 on the first, third and fourth roll, but not on the second roll?"

What is the probability to get 6 in the first roll - 1/6


What is the probability to get not 6 in the secondroll - 5/6


What is the probability to get 6 in the third roll - 1/6


What is the probability to get 6 in the fourth roll - ???

Now continue....

i thought that too with a =.38%

(1/6)*(3/6)*(1/6)*(1/6)=.38 :?:

i thought that too with a =.38% <<<< Incorrect - improper rounding = 0.3858025% = 0.39%

(1/6)*(3/6)*(1/6)*(1/6)=.38 <<< how did you get that?

i mean 5/6..lol. sorry
