Answer:
Option (c) : f' (x) = - 2 / 5x
On a cube, you have 6 faces, therefore you have 1 chance to get 6 and 5 chances not to get 6.
Therefore, the overall probability not to get 6 is 5/6 = 0.8333
If you roll the cube 18 times, the prediction of unsuccessful rolls will be:
18 × 0.8333 = 15
Therefore, you expect to have 15 unsuccessful rolls over 18 total rolls.
