Find P B and D PA or C PBD given the following table A B C 1

Find P( B and D), P(A or C), P(B|D) given the following table.

       A         B     

C    10       11

D    12       13

Solution

There are a total of 10+12+11+13 = 46 observations here.

Thus,

P(B and D) = 13/46 or 0.282608696 [ANSWER]

P(A or C) = (10+12+11)/46 = 0.717391304 [ANSWER]

P(B|D) = 13/(12+13) = 0.52 [ANSWER]
