(a) What is the probability of obtaining tails and a four? (Enter the probability as a fraction.)

Probability of getting a tails is 1/2 (since you can only get heads or tails).

Probability of getting a 4 is 1/6 (since you can get any number between 1 and 6)

So 1/2 * 1/6 = 1/12 of getting both a tails and a 4.
