Mrs R claimed an answer of 1/40, which I agreed with, so it seems that we all have a consensus.
However, young Mr R (who is not a mathematician and has no interest in football) challenged the on-field decision and gave an alternative answer of 2/15.
He has sent me to the VAR screen to review my decision.
Mrs R and I are heading to Manchester today (for the football), so it might take me a while before I respond. In the meantime, the crowd will be kept in suspense without being told a thing. Maybe I’m taking the VAR analogy a bit too literally!
