Can someone please help me!

A regular 6sided die is rolled three times. Find the probability of each event:

a) Three 6s in a row
b) 5,1,even
c) Odd, greater than 2,5
Show all work
I have been looking at examples and trying all night and I can't figure this out.

prob of a 6 = 1/6

so prob(three consecutive 6's) = (1/6)(1/6)(1/6) = 1/216

b) prob(any particular number) = 1/6
so prob(5,1,then even) = (1/6)(1/6)(1/2) = 1/72

c) prob(odd, >2, 5) = (1/2)(4/6)(1/6) = 4/216 = 1/54
