Here is what I have got.

Question:

1. The four major blood groups are designated A, B, AB and O. Within each group there are two types; positive and negative. Find data on the relative frequency of these eight blood groups (as in the general population).

a. Make a table showing the probability of meeting someone in each of the eight groups.

b. For a group of 50 people, how many would you expect to have in each one of these groups?

I have gotten this info :

ABO Type Rh Type

O positive 37.4%

O negative 6.6%

A positive 35.7%

A negative 6.3%

B positive 8.5%

B negative 1.5%

AB positive 3.4%

AB negative .6%

Please help, I have 5 projects to complete by tonight in Statistics and ready to cry. TIA.
