Answer 1

5

Explanation:

since we know that there are 5 different flowers and 4 sets we do

5!=5x4x3x2x1=120

4!=4x3x2x1=24

we divide 120/24 and get {5}

(!) in math factorial means the product of an integer and all the integers below it. EX. 6!=6x5x4x3x2x1

Answer 2

You can make 5 combinations from the set.
