pdf_text[:1000] The document seems to contain a few probability-related questions written in Portuguese. Here's an overview of the first few questions:

1. Question 1: Involves the probability of selecting a set of 3 digits, where the digits range from 1 to 9. It asks for the probability that no digit is repeated in the set of numbers selected randomly. The result should be presented as a fraction in its simplest form.

2. Question 2: Involves drawing balls from a bag containing 6 green balls and 3 orange balls, asking for the probability of:

   • a) Drawing all 3 green balls,
   • b) Drawing 3 balls of the same color, and
   • c) Drawing at least two green balls.

3. Question 3: Involves a box containing 6 blue balls and 4 green balls. The task is to determine the probability of drawing 4 balls from the box, with the outcome of each draw being simultaneous.
