Pr(allsame)=1*1/4*1/4*1/4
pr(not all the same)=1-pr(all same)
I have 4 spinners each divided into 4 equal sections (labeled 1,2,3,4,) what is the probability of not all same? i have tried multiple ways of doing this and get different results and i don't know what is correct. I have tried 1/4*1/3*1/2*1 and got 1/24 but i know this is incorrect because that is the same as 3 spinners instead of 4. I have tried 1/4*1/3*1/3*1/3 and i don't understand that but that's what some website told me to do and got something completely different. HELP!!!!!!!!!!!!!!!!!
