Using it's concept, it is found that the probability of rolling an even number or flipping a tail is of .
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there are 12 outcomes. Of those, 3 result in an even number and a tail, 3 more in an even number but not tail and 3 in a tail but an odd number, hence there are 9 desired outcomes.
Hence, the probability is given by:
