Pls help fast:<br>How many ways can 3 songs be chosen from 12 to create a 3 song ordered play list?

leva [86]

Answer:

1320

Step-by-step explanation:

Total number of songs = 12

Number of songs required to arrange in a play list = 3

It means we have to arrange 3 songs from 12 in the play lines. So, required number of ways is

$Ways=^{12}P_{3}$

$Ways=\dfrac{12!}{(12-3)!}$ $[\because ^nP_r=\dfrac{n!}{(n-r)!}]$

$Ways=\dfrac{12\times 11\times 10\times 9!}{9!}$

$Ways=1320$

Therefore, the required number of ways is 1320.
