MATHEMATICS 7th-Akrabawi HR-A302 Assignments

Today in class, 18 people drew cubes from a cup, noted their color, and then put it back in the cup.  The cup had 55 cubes in it; a mix of only blue, green and yellow cubes.  Here are the results of our 18 draws: 10 yellow, 7 blue, and 1 green.

Your task is to develop a probability model based on our experiment and use that to estimate how many yellow, blue, and green cubes there actually were.  

Remember: your total for your prediction must add up to exactly 55!
