I'm given three sealed unlabelled boxes to choose from called A, B, and C. Suppose these are the contents of the boxes; Box A - 213 centipedes, 43 razor blades, 4 spiders Box B - 101 centipedes, 43 razor blades, 33 spiders Box C - 45 centipedes, 200 razor blades, 50 spiders I choose a box randomly. While closing my eyes, I reach my hand in the box. I pick something at random. My nervous system shuts down so I do not feel what it is. I open my hand. A spider emerges. It is my worst nightmare. What is the probability that the box I picked is Box A, given that the randomly picked object inside turned out to be a spider?
