Two different side of the same dice are shown, the six face of which are numbered 1 to 6. what will be the sum of expected number on the face opposite to the showing 1 ?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 8.
In both dice, 1 and 5 are common, then 3 will be opposite to 4.
Since 2 and 6 are not showing, then 2 and 6 can be opposite to 1.
Thus, the sum of the expected number on the face opposite to the showing 1 = 2 + 6 = 8
