The 2011 national youth risk behavior survey provides insight on the physical activity of u. s. high school students. physical activity was defined as any activity that increases heart rate. here is the probability model obtained by asking, "during the past 7 days, on how many days were you physically active for a total of at least 60 minutes per day? "

what is the probability that a randomly selected u. s. high school student exercised at least 1 day in the past 7 days?

days 0,1,2,3,4,5,6,7

probability, 0.15 ,0.08 , 0.10, 0.11, 0.10, 0.12, 0.07, 0.27

could not attach table so -> this is the table days in colum one with numbers and probability in column 2 with numbers

a) 0.08

b) 0.23

c) 0.77

d) 0.85

e) 0.92
