Hello everyone,

Just need advice how to calculate probability of two samples in a 2 x 4 table.
so say i have two groups (brown haired people and blonde haired people) and the columns are 4 levels on a game. I have the counts for the numbers of people that got to each level. How do I calculate the probabilities for both hair colours? i.e. p1 and p2. Thanks in advance for the help. this is probably simple for everyone, but am stuck. thanks.
