प्रश्न
Two dice are thrown together. The probability of getting the same number on the both dice is
पर्याय
`1/2`
`1/3`
`1/6`
`1/12`
उत्तर
Total number of outcomes = 36.
Getting the same number on both the dice means (1, 1), (2, 2), (3, 3), (4, 4), (5, 5) and (6, 6).
Numbers of favourable outcomes = 6.
∴ P(getting the same number on both dice) =`("Number of favourable outcomes")/"Number of all possible outcomes"`
=`6/36 = 1/6`
Thus, the probability of getting the same number on both dice is `1/6`.
Hence, the correct answer is option `1/6`.
