Answer:
[tex]P(X = 1,2,...,20) = \frac{1}{20}[/tex].
Step-by-step explanation:
Each scenario is the number of the card drawn. The number can be 1,2,3,4,...,20.
The probabilities of each number is uniform, that is, each number has the same probability of being drawn, since there are 20 cards, one with each number.
In all, the probability of a number being drawn is
[tex]P(X = 1,2,...,20) = \frac{1}{20}[/tex].
