These problems are flawed in that the cube ought to have been shown owned by X,
so X could conceivably get another roll.

For the top problem, pip count tells us to prepare for 4-4 or better.  6/4(2)
5/3(2) is fine.

For the second, pip count tells us to prepare for 4-4 or better.  However you
can't be off on 4-4 because 4-4 is exactly enough pips and you can't port all
four pieces to the 4-point.  So we try to prepare for 5-5 or better.  6/off is
fine.  6/1 6/5 is also fine.
