If you calculate the probability of obtaining a number <3,
will you be including the probability that a "2" was rolled ?
Are these events "mutually exclusive" ?
Is 4 odd?
Hence if you calculate the probability of landing an odd number,
will that include the probability of obtaining a 4?
Are these events mutually exclusive?
Hence, what do we do with the probabilities of both events to calculate the overall probability of "odd" or "4" ?
