😀Cricket is traditionally played with a dark red ball. When they play in the dark under lights, they can’t see a red ball, so they use a pink or white ball.

Good/appropriate use of the British term bollocks.

I hope this helps...
If you picked the winner first (prob 1/3), you lose by switching
If you pick a loser first (prob 2/3), Monty is forced to pick the other loser, and you are left with the winner.
So, if you switch, you win so long as you pick a loser to start with - so 2/3 of the time
