An experiment consists of first rolling a die and then tossing a coin.

How many elements are there in the sample space?
12

Let A be the event that either a 1, 2, 3 or 4 is rolled first, followed by landing a tail on the coin toss.
P(A) = Present your answer as a decimal rounded to four decimal places.

I've calculated my sample space, but I don't know how to go about the second question. What formula would I use?

Thanks in advance.
