The total number of shirts is 2 + 1 + 1 + 1 = 5.
In both cases (a) and (b), the same formula works
P = .
In case (a), the number of favorable outcomes is 2+1 = 3.
In case (b), the number of favorable outcomes is 2+1 = 3 (the same).
THEREFORE, in both cases P = = 0.6 = 60%. ANSWER
Solved and explained.

Note that the problem is very poorly constructed; as presented it can't be answered definitively.
The response from the other tutor assumes that the short-sleeved shirt is neither pink nor purple nor green, making a total of 5 shirts.
But if the short-sleeved shirt is either one of the pink shirts, or the purple or the green shirt, then there are only 4 shirts, making the answers to the questions different.
ANSWERS: We don't know, because the given information is not defined well enough.
