Answer: The correct elements are (B) (H, 6) and (T, 4).
Step-by-step explanation: Given that Sam is playing a game where he flips a coin and rolls a number cube labeled 1 through 6.
He listed the possible outcomes in the sample space as follows:
S' = {(H, 1), (H, 2), (H, 3), (H, 4), (H, 5), (T, 1), (T, 2), (T, 3), (T, 5), (T, 6)}.
We are to find the two elements that he left out while writing the sample space.
The complete sample space is given by
S = {(H, 1), (H, 2), (H, 3), (H, 4), (H, 5), (H, 6), (T, 1), (T, 2), (T, 3), (T, 4), (T, 5), (T, 6)}
All the elements of S are in S' except (H, 6) and (T, 4).
So, Sam left out the elements (H, 6) and (T, 4).
Thus, (B) is the correct option.
