Question

A 5cm long stick is dropped from a large height onto a sheet of graph paper. The grid on the graph paper has 5 cm squares. What is the probability that the stick falls across the edge of a grid square?

You may assume that the stick is thin.

Answer 1

According to the basics of probability, the outcome should be equally likely that mean chances of all outcomes should be same. In this case the stick falls across the edge of a grid square and not falls across the edge of grid square.

Answer to this question will be based on taking a large sample and repeating the experiment again and again.

1. The probability will be 1/2 if have equally likely chances.

2. The probability will be 1 if falls on edges of grid squares.

3. The probability will be 0 if not falls across the edge of grid square.
