Deal or No Deal UK - £100000 winner 4/4

This is part 4/4 of the episode of D.O.N.D. in which the contest, Betty, wins £100000, after many other contestants before her had failed miserably because they had either dealt too soon, not soon enough, or not at all, and had a small amount of money in their box. This is just what the remaining contestants needed, to boost their confidence and win more money in future.
