Answer 1

I think four green faces and three red faces.

I hope it helps

Answer 2

 Considering uniformly distributed outcomes, we get 4 greens and 2 reds in six throws. Then in one more throw, green is more likely.

So, option (C) is correct.




As probability of occurrence of green face 

=4/6=2/3=4/6=2/3,


and probability of occurrence of red face


 =2/6=1/3=2/6=1/3.


If the die is rolled 6 times,

then expectation of green and red faces are 4 and 2 respectively.

But die is rolled 7 times,

so I prefer 5 green and 2 red faces as green faces has more probability than red faces.
