You roll a 6 sided cube, what is the probability of rolling a multiple of 2 or a number greater than 3?

Okay so here we go,

Multiples of 2 on a 6 sided cube are:

2, 4 and 6 which in probability terms is 3/6 (simplifies to 1/2)

Numbers greater than 3 are: 4, 5 and 6 which in probability terms is 3/6 (simplifies to 1/2)

The question says 'or' which means addition of probabilities.

1/2 + 1/2 = 1

Your answer is 1

The probability of rolling a multiple 2 or a number greater than 3 is 1/3
