The product of the given numbers is 38.4888. Rounding this to two significant digits gets you 38.
Using it's concept, it is found that the probability of rolling an even number or flipping a tail is of
.
<h3>What is a probability?</h3>
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:
