Answer:
In 120 ways pieces can be arranged
Step-by-step explanation:
We have given that a pianist plans to play 5 pieces at a recital
We have to find in how many way she can arrange these pieces in the program
We know that for arrangement we use permutation.
So for total number arrangement of pieces we have to find permutation of 5
So total number of arrangement [tex]=5!=5\times 4\times 3\times 2\times 1=120[/tex]
So in 120 ways pieces can be arranged
