Answer:

20

Explanation:

We are given that Emily is packaging her bags for her vacation.

She has unique Faberge eggs=6

But eggs fit in her bag=3

We have to find the number of different groups of 3 Faberge eggs can she take.

Combination formula


nC_r=(n!)/(r!(n-r)!)

n=6, r=3

Using this formula


6C_3=(6!)/(3!(6-3)!)=(6* 5* 4* 3!)/(3!3* 2* 1)


6C_3=20

Hence, Emily can takes 20 different groups of 3 Faberge eggs .
