How to make the reflectance random ? READ BELOW

this is just an example, so you don't say it's a "request" don't change this script i just need 5-11 lines to know how to do it ?

	if target ~= nil then
		if ready == true then
			ready = false
			Laser(turret.Position,target.Character.Torso.Position)
			target.Character.Humanoid:TakeDamage(set.damage)
			target.Character:findFirstChild("Head").Reflectance(math.random)
			target.Character:findFirstChild("Torso").Reflectance(math.random)
			target.Character:findFirstChild("Right Arm").Reflectance(math.random)
			target.Character:findFirstChild("Right Leg").Reflectance(math.random)
			target.Character:findFirstChild("Left Arm").Reflectance(math.random)
			target.Character:findFirstChild("Left Leg").Reflectance(math.random)
			wait(0.1)
			target.Character:findFirstChild("Head").Reflectance = 0
			target.Character:findFirstChild("Torso").Reflectance = 0
			target.Character:findFirstChild("Right Arm").Reflectance = 0
			target.Character:findFirstChild("Right Leg").Reflectance = 0
			target.Character:findFirstChild("Left Arm").Reflectance = 0
			target.Character:findFirstChild("Left Leg").Reflectance = 0
			turret.Fire:Play()
			wait(set.shotcooldown)
			ready = true
		end
	end
	target = nil
end)

thanks !
