(D)

Atleast one even and one odd -

EOE - 3 ways (2 evens one odd)

OOE - 3 ways (2 odds one even)

3(1/8) + 3(1/8) = 6/8 = 3/4

Simpler way to explain is this :

If you roll a die 3 times , and if u are only looking for even and odd (i.e. 2 outcomes) then the number of results is 2^3 = 8. Out of which the only times its NOT a valid result is 3 evens or 3 odds. So if u remove these two results the probability is 6/8 = 3/4.
