The Educate Cube video explains the RAND function, which generates a random float value between 0 and 1. The syntax involves writing `SELECT RAND()` and optionally naming the column. The function always returns a different decimal number between 0 and 1 each time it runs.
It can also be multiplied by any number to adjust the range. The video demonstrates this with practical examples and concludes with a request to like, share, and subscribe to the channel.
