<h2>Answer:</h2>

The part of the video that was not of his children is:

         85 minutes    OR   1 hour and 25 minutes.

<h2>Step-by-step explanation:</h2>

It is given that:

Ali was reviewing his family video.

The tape totaled 2 hours and 37 minutes.

Now we know that:

1 hour=60 minutes

This means that:

2 hours=2×60 minutes

i.e.

2 hours= 120 minutes

Hence, 2 hours and 37 minutes= 120+37 minutes

i.e.

2 hours and 37 minutes= 157 minutes.

Video of his children totaled 72 minutes.

This means that the part of the video not of his children is:

Total time of video-Time of video of his children

=  157-72

= 85 minutes or 1 hour and 25 minutes

157-72=85 so there was not 85 minutes or 1 hour and 25 minutes of childrens video

amid [387]

The probability that all five end up in alphabetical order is; 1/120.

<h3>What is the probability that the rack ends up in alphabetical order?</h3>

To evaluate the given probability; first, the number of possible arrangements is;

17P5 = 742,560 possible arrangements.

However, the chance of an alphabetical order arrangement in each case is; 1 out of 5! possible arrangements.

Hence, we have that the number of possible alphabetical arrangement is; (1/120) × 742,560 = 6188.

Hence, the required probability is; 6188/742,560 = 1/120
