P(black or summer) now it's a mutually exclusive event do u know what is mutually exclusive event

anonymous · Answer

yes

usman1995 · Answer

so in exclusive events we multiply the probabilties or add them??

anonymous · Answer

multiply

usman1995 · Answer

no u r wrong  
We add when we want the probability that at least one (i.e. A or B or ...) of several mutually exclusive events occurs. Mutually exclusive events are those that cannot occur together. For instance, when rolling a die, you can't get 1 and 2 at the same time. Therefore, rolling a 1 and rolling a 2 are mutually exclusive events. Thus, the probability of rolling a 1 OR a 2 is the sum of their individual probabilities.
