Problema Solution
You throw a d20 numbered from 1 to 20 find the probabilty for the number called x : P(x
Answer provided by our tutors
"a d20" is assumed to be a "20-sided dice", so we assume here that this is simply an extension of a regular 'roll the dice' question but instead of 6 sides there are 20
the probability of rolling any single number, given a fair die, is:
P(x) = 1/20 = 0.05
there is a 5% chance of rolling the number 'x' where 1<=x<=20
