below are the results of tossing a number cube 8 times find the experimental probability of tossing an even number. 3,4,1,2,5,1,6,5
1. 1/4
2. 3/8
3. 1/2
4. 5/8
so 3/8
I am the real ms.Yates all of you will be in big trouble when i find you
Its not called cheating if you are checking someones answers.Your telling people to be ashamed and there's people out their trying to explain and help people, yet your telling them to be ashamed.And Ms. Yates tell us why your here.Clearly not here to help!
Like if u need to get your math grade up
I would say 3/8.
You got three even numbers (4 , 2 and 6) out of eight tosses.
Yes, please stop impersonating me. It is really rude and unacceptable
yall are ruthless
"Ms. yahtzeenuts"
BAHAAHAHAH
U guys are making me laugh so hard rn-
@Ms. Yates, u should be the one who is ashamed. Ur over here stalking us. Smh.
