Random bullet directions

I want to make it so my enemies are able to spawn three objects and send them in three separate random directions. I know how to instantiate prefabs but am unsure how to pick a random 360 degree direction for each one and make them follow their own path.

the easiest way to pick a random direction may be to just generate a random Vector3:

var randomX = Random.Range(0,360);

var randomY = Random.Range(0,360);

var randomZ = Random.Range(0,360);


var randomDir = Vector3(randomX,randomY,randomZ);

...

clone = Instantiate(projectile, transform.position, transform.rotation);

    clone.velocity = randomDir * speed;
