The Joints are:
brown hair and brown eyes:12

don't have brown hair and brown eyes:1
the marginals are:
Total of brown eyes:22
Total of other than brown eyes:3
total of brown hair:14
Total of other than brown hair:11
The Joint Probabilities are:
the probability of brown hair and brown eyes:48%
the probability of brown eyes but not brown hair:40%
the probability of brown hair but not brown eyes:8%
the probability of other than brown eyes and brown hair:4%
The marginal probabilities are:
The total of brown eyes:88%
the total of other than brown eyes:12%
the total of brown hair:56%
