If you want to visualize them in "enumeration of cases".
The complete cases for the choices is:
Problem-1:
1) You pick goat#1, Monty opens goat#2
2) You pick goat#2, Monty opens goat#1
3) You pick car, Monty chooses a goat of his liking
Problem-2:
1) You pick goat#1, Monty opens goat#2
2) You pick goat#2, Monty opens goat#1
3) You pick car, Monty opens goat#1
4) You pick car, Monty opens goat#2
5) You pick goat#1, Monty opens car
6) You pick goat#2, Monty opens car
We know Monty didn't pick a car, that reduces it to:
Problem-1:
1) You pick goat#1, Monty opens goat#2
2) You pick goat#2, Monty opens goat#1
3) You pick car, Monty chooses a goat of his liking
Problem-2:
1) You pick goat#1, Monty opens goat#2
2) You pick goat#2, Monty opens goat#1
3) You pick car, Monty opens goat#1
4) You pick car, Monty opens goat#2
Or, 1/3 for Problem-1, 2/4 (=1/2) for Problem-2
