MY QUESTION: What is the discussion and Interpretation of Results?

Data and Results:

A. Measurement of tails using Tossing of coins

EXPERIMENTAL PROCEDURE:

1. With the use of a marking pen, label each coin with the numbers 1 to 3.
2. Toss the 3 coins together and note the coins with tails.
3. Repeat step 2 ten times while noting the number of coins resulting to tails.
