factors of 40 : 2,4,5,8,10,20
but only 5, 8, 10 fall within our domain
So numbers which are even OR a factor of 40 are:
5,6,8,10,12,14 --> 6 of them
prob(of your event) = 6/10 = 3/5
but only 5, 8, 10 fall within our domain
So numbers which are even OR a factor of 40 are:
5,6,8,10,12,14 --> 6 of them
