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
![[\because ^nP_r=\dfrac{n!}{(n-r)!}]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%5EnP_r%3D%5Cdfrac%7Bn%21%7D%7B%28n-r%29%21%7D%5D)
Therefore, the required number of ways is 1320.
Answer:
The probability is 435/6,806
Step-by-step explanation:
Firstly, the total number of coins in the jar is
13 + 15 + 29 + 26 = 83
The probability of selecting a dime is 15/83
Now we want to grab a nickel
Since we already selected a dime and we did not replace it, the number of total coins in the jar will be 83-1 = 82
So the probability of selecting a nickel this time is
29/82
So the total probability of the event in the described order is;
15/83 * 29/82
= 435/6,806
