Lottery - as in random, by chance, without regard to intention

From The Times:

...[T]he first local authority-wide experiment of allocating places at oversubscribed schools by lottery has backfired.

Figures to be published today by Brighton and Hove council will show that 22 per cent of children have missed out on their first choice of school this year, compared with just over 16 per cent under previous admissions rules. Its mission was to bring greater fairness and parental choice.

Whodathunkit, eh? It's a lottery.
