Possible Outcomes

An experiment consists of rolling a fair die and flipping a fair coin. What is the probability of getting a number divisible by 2?

Lets think first, the die has 6 faces and a coin has two.
Now, we figure out what are the numbers on the die that are divisible to 2.
1, 2, 4, and 6 all are divisible to 2
and the coin that has no numbers on it but lets say tails is 1 and heads is 2 because there are only two faces on a coin.
so the only one is heads.

So now we have our answers 5/7
