## anonymous 5 years ago Okay so I need this WITH EXPERIMENTAL PROBABILITY!!! How would I set it up with a spinner?????? You take a three question multiple choice test. Each question has four choices. You don't know any of the answers. What is the expirimental probability that you will guess exactly two out of three correctly?

i will type here if you like.

I did. I wasn't there for the lesson, so how would I use this online spinner to do this? THat last one i spun 100 times and recorded, but that wont work for this

ok i guess you take a spinner that has 4 equal parts, one is correct and the rest are not. so $\frac{3}{4}$ of the area is one color and $\frac{1}{4}$ is a different color. spin 3 times and record the number of times you get it "right"

then repeat

in any case the "theoretical " probability is not $\frac{3}{64}$ it is $\frac{9}{64}$
