Consider we need to find the number of elements in the sample space.
Given:
Jo flips a coin {H, T}; then rolls a 6-sided die {1, 2, 3, 4, 5, 6}.
To find:
The number of elements in the sample space of this experiment.
Solution:
Jo flips a coin {H, T}; then rolls a 6-sided die {1, 2, 3, 4, 5, 6}.
So, the sample space is
S = {H1, H2, H3, H4, H5, H6, T1, T2, T3, T4, T5, T6}
So, the number of elements in the sample space is 12.
Therefore, the correct option is C.
