Hi,

Use the following contingency table to answer

      x     y     T

A    24    31     55

B    13    66     79

T    37    97    134

1. What is P(X)= 37/134

2. What is P(X or Y) = 1

3. What is P(X or A) = 37/134 + 55/134 - 24/134

4. What is P(X|A) = %2824%2F134%29%2F%2855%2F134%29+=+24%2F55
