Answer:
P(13,2) = 169
Explanation:
We have to calculate the combinations for left and right shoe considering is not the same having a right shoe blue and left red than having a right shoe rend and a left red.
there are 13 pairs from whcih she will take a single pair:
[tex]P(n,r) = n^{r} \\[/tex]
where:
n = number of pair = 13
r = shoes = 2 (one on each foot)
[tex]P(n,r) = 13^{2} \\[/tex]
P(13,2) = 169
