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.

A bag has identical balls of these colors: 1 white, 6 red, 9 green, and 3 purple. Without looking, a ball is drawn from the bag. You would most likely get a

a. green ball
b. purple ball
c. red ball
d. white ball

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 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
