What are the chances?

Allow me to set the scene. I’m in my kitchen about to put on my marigolds and commence the washing up. “Relocation Relocation” is playing in the living room. Suddenly I hear Kirsty say “Oh Phil, any excuse to get your top off.” In the name of science I decide to go and have a look at Phil in a hot tub. As I’m gazing at the TV I realise that my marigold will not fit over the wooden bangle I’m wearing (a present from my sister’s trip to Thailand). I remove said bangle and lob it at the sofa whilst still transfixed by Phil in the hot tub. It lands at one end of the sofa and then (in slow motion) rolls the full length of it (a good three feet or so), somehow turns when it reaches the other end, then falls off the front, landing directly on the full pint glass of water on the floor, completely shattering it into microscopic pieces which I will be picking out of the carpet for weeks to come.
