Q. The primary aim of a study by Carter et al. was to investigate the effect of the age at onset of bipolar disorder on the course of the illness. One of the variables investigated was family history of mood disorders. Family History of Mood Early =18(E) Later >18 (L) Total Disorders Total Negative (A) 28 35 63 Bipolar disorder (B) 19 38 57 Unipolar (C) 41 44 85 Unipolar and bipolar (D) 53 60 113 Total 141 177 318 Above table shows the frequency of a family history of mood disorders in the two groups of interest (Early age at onset defined to be 18 years or younger and later age at onset defined to be later than 18 years). Suppose we pick a person at random from this sample. What is the probability that this person: a. Will be 18 years old b. Will be negative (A) or Unipolar (C) c. Will be an Early age of onset subject (E) or will have no family history of mood disorders (A)
