Sorry my mouse keeps moving and I type on the wrong one...
I got 1/3 for red I got 2/3 for yellow and 1/3 for green but they was wrong, Since you only have three colors I put that on the bottom and went by equal numbers on top. Can someone explain this to me.
A. I put 0.27 b. 0.36 c. 0.56 because I multiplied them both together. d. I put 0.56 also but that was wrong????? I got the whole thing wrong
I have done that to another one and posted how I worked it out, so if you don't mind will you look at it and see if I am on the right track. I have done several but I found formulas to use from the book but sometimes I do not understand what the book has..
I worked this one 0.25/0.59 and got the answer of .42372. Could not find the formula to see if this one you added, multiplied, or subtracted the way it was written.
