This is what I got for part (a) F(x)= 3Ck * 0.5^3 F(y)=3Ck * 0.667^3 F(z)=3Ck * 0.167^3 Now for part (b) I have some problems, I don't know if I got all the possible outcomes RRR RRG RGR GRR GGG GGR GRG RGG RGY RYG GYR GRY YRG YGR YYR YYG YRY RYY YGY GYY YYY I...

Yes, thank you. I put it into the formula and it gave me the correct answer :)

A box contains 12 marbles. Six of the marbles are red, four are green, and two are yellow. Suppose that you choose three marbles at random. let x be the number of red marbles in the sample, y be the number of green marbles, and z be the number of yellow marbles. a. Give the precise formulas...

I know this problem is simple enough but I can't get the hang of it Find the electric field at point A in the diagram if (a) q1=2.00 μC and q2=3.00 μC. (b) q1=2.00 μC and q2= -3.00 μC. Thank you. P.S. If you can explain how you solved the problem that would be great. I'd really like to know...
