To make text invisible, set its ink color to the background color.

To pick some random Labels, init a global LabelList to a list of your 4 Label components.

Use the enclosed randoms value procedure to generate a list of 2 random numbers from the range 1-4.

Make all the Labels in LabelList Visible. Then
use the items in the list of 2 random indices as indices into LabelList for the Labels you want to make invisible.
