Answer:
{CM} {CD} {CW} {MC} {MD} {MW} {DC} {DM} {DW} {WC} {WM} {WD}
Explanation:
The sample space is all the possible results that can be obtained from a randomized experiment.
In this case, the experiment is to select two chocolates out of 4.
If we have 4 chocolates of different types {C, M, D, W}
and we select 2, then (taking into account the order in which she eats the chocolates} the possible results are:
{CM} {CD} {CW} {MC} {MD} {MW} {DC} {DM} {DW} {WC} {WM} {WD}
There are 12 possible results for this experiment.
