|Assume that there are two jury pools, each
with 100 people. One of the pools has 70 whites and 30
blacks. The other pool has 30 whites and 70 blacks. 12
names are drawn from one of the two pools. 8 of the people drawn
are white and 4 are black. What is the probability that the
drawing came from the pool that included 70 whites and 30 blacks?
