Tony throws the dice once.
Mandarinka [93]

Answer:

The outcomes are given means

1H: the dice rolled into a 1, and the result of the coin flip is heads.

Then, the list will be:

1H, 2H, 3H, 4H, 5H, 6H, 1T, 2T, 3T, 4T, 5T, 6T

Where T means tails, H heads, and each number corresponds with one of the possible numbers of the dice.

You also can calculate the number of possible outcomes by multiplying the total outcomes of each experiment.

For the dice, we have 6 outcomes

for the coin, we have 2 outcomes.

From the coin and the dice at the same time, we have 6*2 = 12 outcomes, which coincides with the 12 possible outcomes listed above.
