How do I "RANDOM" sprite animations?

hi, i have one sprite in my game with differents animations

HOW to tell to my game to play random animations but ONLY the animations "B1 B2 B3 B4 B5" not the "A0"

thanks

Set animation to random(B1,B2,B3,B4,B5)?

Play random(B1,B2,B3,B4,B5)?

That would be play: choose("B1","B2","B3","B4","B5")

whoops something happens IT PLAY randomly the animations but it does wierd placements :s

ok solved

you wold also have to create a check list for each animation if animation is playing b1 choose("B2","B3","B4","B5") etc and when ur animation is on B1or ,b2,b3,b4,b5 not to get the same animation again and to create the glitch where its going to pick itself!
