dalvyx [7]

Answer:

Step-by-step explanation:

GIVEN: Tiffany is packing her bags for her vacation. She has 8 unique toy animals, but only 4 fit in her bag.

TO FIND: How many different groups of 4 toy animals can she take.

SOLUTION:

Total unique toy animal Tiffany has =8

Total animal that fit in her bag =4

Now,

Tiffany has to select 4 toy animals from 8 animals.

Number of ways of selecting 4 toy animals =^8C_4

                                                                       =\frac{8!}{4!4!}

                                                                       =70

Hence Tiffany has 70 different ways to select group of 4 unique toys.
