In a survey, 48% of the people said they enjoy biking, 52%said they enjoy spin classes, 25% said they enjoy biking and spin classes. Which conclusion is correct for the group of people surveyed?  

• The events are independent because 0.48 x 0.52 = 0.25

   

• The events are independent because 0.48 + 0.52 = 0.25

• The events are dependent because 0.48 + 0.52 = 0.25

• The events are dependent because 0.48 x 0.52 = 0.25
