In this problem you are given 71 objects each of which satis
In this problem you are given 71 objects, each of which satisfies either condition A or condition Ac , and each of which also satisfies either condition B or condition Bc . If one object is selected at random (each object equally likely), fill in the probabilities of the table below.
Solution
Consider:
Thus,
P(A) = 32/71 [ANSWER]
P(Bc) = 38/71 [ANSWER]
P(B|A) = 20/32 = 5/8 [ANSWER]
P(A|B) = 20/33 [ANSWER]
| A | Ac | Total | |
| B | 20 | 13 | 33 |
| Bc | 12 | 26 | 38 |
| Total | 32 | 39 | 71 |
