On the other hand, if the smaller set is entirely contained within the larger set, i.e.
Remark: in the solution, the word Combination is used in the daily usage of the word, not in the combinatorial (mathematical) language.
Let the available 4 base colors be
,
the available 6 accent colors be
,
and the available 2 fonts for the embroidery be
,
so we have 4 b's, 6a's and 2 e's.
The event that Ray and Lilly design identical shoes can happen in the following way:
Ray has in total 4*6*2=48 possible combinations, and in each of these combinations, Lilly makes the same exact combinations of the 3- b's, a's and e's.
The sample space is 48 possible combinations of Ray * 48 possible combinations of Lilly = 48*48
(among these there are 48 matches of the combinations)
Thus P(designing identical shoes)=48/(48*48)=1/48=0.02
Answer:0.02
