Write a function to give arbitrary probabilities (totalling 100%) to each face of a six-sided die.

P(A) = N/0
where P(A) equals Probability of any event occurring
N is the Number of ways an event can occur and
0 is the total number of possible Outcomes

P(A) = 1/6

Plainly the probability of rolling a six with a single six-sided dice is one event in which it lands with six uppermost, divided by six possible outcomes from a single throw, or one sixth (16.66 per cent).
