A coin is flipped, and a standard 6-sided die is rolled. Create a list to
represent the sample space.
The coin and die can fall any of these 12 ways:
H1, H2, H3, H4, H5, H6, T1, T2, T3, T4, T5, T6
What is the probability of the coin landing on tails and rolling an odd number on the dice?
These 3 ways:
T1, T3, T5
out of the 12 possible ways they can fall.
That's 3 ways out of 12 or 3/12 or 1/4.
