प्रश्न
A die is rolled twice. Find the probability that 5 will come up both the times.
उत्तर
Total number of outcomes = 36.
Cases where 5 comes up on exactly two times is (5, 5).
Number of such cases = 1.
∴ P(5 will come up both the times) = `("Number of favourable outcomes")/"Number of all possible outcomes"`
`= 1/36`
Thus, the probability that 5 will come up both the times is `1/36`.
