AI Thread Summary
To determine the most likely color of a ball drawn from the bag, one must consider the quantity of each color present. The bag contains 1 white, 6 red, 9 green, and 3 purple balls, making green the most prevalent color. Given the higher number of green balls, it is statistically most likely that a green ball will be drawn. The discussion emphasizes using common sense and basic probability to arrive at the conclusion. Understanding the distribution of colors is key to solving this problem effectively.

Please show us what you have tried and exactly where you are stuck.

We can't help you if we don't where you are stuck.
 
You title this "I need a formula to calculate this" but this is really a matter of common sense! If there were 1000 red balls and 1 white ball, and you draw one at random, what color is it most likely to be? Why? Apply that idea to this problem.
 

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...

Thread 'Six Pencil Puzzle'

Is it possible to arrange six pencils such that each one touches the other five? If so, how? This is an adaption of a Martin Gardner puzzle only I changed it from cigarettes to pencils and left out the clues because PF folks don’t need clues. From the book “My Best Mathematical and Logic Puzzles”. Dover, 1994.
