Mutually exclusive events can't happen at the same time

ganeshie8 · Answer

look at option a :
are there any even numbers in multiples of 3 ?

anonymous · Answer

no

ganeshie8 · Answer

think again :
6 = 3*2, which is an even number and also a multiple of 3, right ?

anonymous · Answer

right....

anonymous · Answer

would 12 be one too?

ganeshie8 · Answer

Exactly ! so can we safely eliminate option A ?
cuz "even numbers" and "multiples of 3" are not mutually exclusive.

anonymous · Answer

yes

ganeshie8 · Answer
