Winona asked randomly selected students in

her middle school "Do you like the school
lunch?" Of the 240 students she asked, 75
said no and 165 said yes. What are the
experimental probabilities of getting the
answers no and yes, based on Winona's
results?

  • Sample space=S=240
  • N=75
  • Y=165


\\ \sf\longmapsto P(N)=(75)/(240)=(25)/(48)\approx 2


\\ \sf\longmapsto P(Y)=(165)/(240)


\\ \sf\longmapsto P(Y)=(33)/(48)


\\ \sf\longmapsto P(Y)=(11)/(16)
