Thanks. yes, that's my answer too. My tree is still ok but the probabilities on the branches are not equal.
Hope I haven't confused you with my earlier post.
Hi Skyblast72 and bobbym,
Hold on, there are many incorrect assumptions in those statements.
Math is hard. Get that sunk in first. It takes a lot of effort and practice. I have been doing it for 100 years and still am lost.
What good would that do you? Then there would be two dummies on this forum. Stick with your own mind you are better off. Check this out:
Ok I used the diagram. I never know when to use which formula!!! I'll just be happy to pass this class, it's so frustrating. Wish my mind worked like yours!!
That is a commitee problem and there is a formula for those.
4th one with tree diagram
What question are you working on?
.38 is what I got Thanks
I get 16 using the tree diagram
That's what I got too.
There are formulas for this but I think you will get a better understanding if you see a diagram.
Later edit. This isn't right! See my post 34 for the corrected version.
I got m=10
Ok. I'll still be here.
