उत्तर
If A and B are independent events such that P(A) = p, P(B) = 2p and P(Exactly one of A, B) =`5/9`, then p = `1/3, 5/12`.
Explanation:
p = `1/3, 5/12` ....`[(1 - "p")(2"p") + "p"(1 - 2"p") = 3"p" - 4"p"^2 = 5/9]`

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 |
