Solution

The correct option is C
34.72%
Probability of rolling 616
Probability of rolling exactly one 6 → one 6 and 2 non 6.
Required probability =3C2(16×56×56)=75216=2572
Percentage probability =2572×100=34.72%

रोलिंग की संभावना 616
ठीक एक 6 → एक 6 और 2 गैर 6 रोल करने की संभावना।
आवश्यक प्रायिकता =3C2(16×56×56)=75216=2572
प्रतिशत प्रायिकता =2572×100=34.72%
