I guess 1/216....... err not sure!

A die is rolled thrice. Find the probability of getting one six only.

1/6 x 5/6 x 5/6 = 25/216
25/216 x 3 = 25/72

I guess 1/216....... err not sure!

I guess 1/216....... err not sure!

If i am not wrong then it should be like this:
Probability of getting six each time = 1/6
probability of getting any other number but not six = 5/6
So probability of getting six once = 1/6 x 5/6 x 5/6 = 25/216

 

[areeba fatima]

1/6 x 5/6 x 5/6 = 25/216
25/216 x 3 = 25/72

why did you multiply it with 3?
