If A and B are two events and A ≠ Φ, B ≠ Φ, then ______.
विकल्प
P(A|B) = P(A).P(B)
P(A|B) = `("P"("A" ∩ "B"))/("P"("B"))`
P(A|B).P(B|A)=1
P(A|B) = P(A)|P(B)
उत्तर
If A and B are two events and A ≠ Φ, B ≠ Φ, then P(A|B) = `("P"("A" ∩ "B"))/("P"("B"))`.
Explanation:
Given that: A ≠ Φ and B ≠ Φ
Then P(A|B) = `("P"("A" ∩ "B"))/("P"("B"))`

Two hundred patients who had either Eye surgery or Throat surgery were asked whether they were satisfied or unsatisfied regarding the result of their surgery
The follwoing table summarizes their response:
| Surgery | Satisfied | Unsatisfied | Total |
| Throat | 70 | 25 | 95 |
| Eye | 90 | 15 | 105 |
| Total | 160 | 40 | 200 |
