A sample of 1000 persons screened for a certain disease is distributed
according to height and disease status resulting from a clinical exam
as follows:

DISEASE STATUS

None Mild Moderate Severe Totals
|-------|---------|------------|----------|
Tall | 122 | 78 | 139 | 61 | 400
|-------|---------|------------|----------|
HEIGHT Med | 74 | 51 | 90 | 35 | 250
|-------|---------|------------|----------|
Short | 104 | 71 | 121 | 54 | 350
|-------|---------|------------|----------|
300 200 350 150 1000

What would you estimate from the above table to be the probability
of being medium or short in height and having moderate or severe
disease status?

a. 600/1000 * 500/1000 d. 300/600
b. 300/500 e. 800/1000
c. 300/1000
