There are 100 people total. 30 of them are from group A, 70 are from group B. And group A and B are things you cannot switched in-between from.

There are two sets of probability of death for individuals in the groups:

1. 50% for A, 50% for B

2. 90% for A, 10% for B

You are from one of the groups, but you don’t know which group you belong to. There are equal probability for you to belong to A or B. Would you choose option 1, or option 2?
