I believe the first answer is 1/6 and the second is 1/3.
If it is a 6 sided dice then there is a 1/ 6 chance she rolls a 5, that doesn’t change based on the amount of times she rolls it. If she is trying to roll a 1 OR 2 there is 2/6 chance she will roll one of the numbers, which can be simplified to 1/3.
