Noel opens box 23 and reveals

MONEY BACK

Wouldn't have mattered then. Fair enough result.

No complaints about that game.

If she had known the % at five box (doubt it) might have been a different answer. I'd expect she would have dealt at two box.

I would highly doubt anyone is going to know the %. Even if Linda did, she'd probably still deal.

Why was this in a 65 minute slot though?

Probably for all the times the banker rang into the game. I lost count in the end

Apart from that, a game well played by Linda, with a sensible 5-box deal and in the end, she didn't miss out on as much as she could have done.

Working out the % of what colour amount the box will contain with four reds and a single blue, I'm going to stick my neck out and say that 999 out of 1000 contestants will know that. It's pretty elementary stuff.
