and there is only one chance of it landing on the top face of the cube that why iguessed 1/3

Answer 5

**that is why i guessed 1/3

Answer 6

yeah, there are 3 events.we knowed that the space set of a cube = {1,2,3,4,5,6}, so the number all events = 6
now, use the formula of the probability of a event is :
P(A) = numbers of events/numbers all events = 3/6 = 1/2
