Exercise

The prior

Suppose we have two different region vectors (you can see the resulting spinners on the right!):

# Regions for Spinner A
regA <- c(1, 2, 3)

# Regions for Spinner B
regB <- c(3, 2, 1)

Imagine you have a box which contains many different spinners, some of which look like Spinner A, and some like Spinner B. In this case, a prior will be represented as (Probability of Spinner A, Probability of Spinner B).

If you get a friend to choose a spinner at random, which of the following will be a reasonable prior for Spinner A and Spinner B?
