The probability of selecting a multiple of 5 or an even number is P = 2/5, so the correct option is F.
How to find the probability?
The probability will be equal to the quotient between the number of days that are multiple of 5, and the total number of days in September.
September has 30 days, and the multiples of 5 or even numbers are:
{2, 4, 5, 6, 8, 10, 12, 14, 15, 16, 18, 20, 22, 24, 25, 26, 28, 30} so 6 days are multiples of 5.
Then the probability of the event is just:
P = 18/30 = 6/10 = 2/5
So the correct option is F.
