Which of the following experiments could be used to simulate an event in which the probability of success, P(success), is 0.60, and the number of successes out of 20 events is desired?
A. Count out 65 yellow beads and 35 pink beads. Randomly select 20 of these beads. Let a yellow bead represent a success and a pink bead represent unsuccessful.
B. Roll a 10 sided die. Let 1–5 represent a success and the values 6–10 indicate unsuccessful. Roll the die 20 times, once for each event.
C. Use a random number table consisting of the digits 0–9, with digits 0 through 3 representing a success and the remaining digits 4 through 9 representing unsuccessful. Choose 20 digits, one for each event.
D. Use a spinner that is divided into 5 equal parts. Choose 3 colors for a success; the other 2 colors will represent unsuccessful. Spin the spinner 20 times, once for each event.

The school track has eight lanes. each lane is 1.25 meters wide. the arc at each end of the track is 180. the distance of the home straight and the radii for the arcs in the 1st 4 lanes are given. s=85m r1=36.5m r2=37.75m r3=39m r4=40.25m part one: find the radii of lanes 5 through 8 of the track. show your work. part two: if max ran around lane one, how far did he run? show your work and explain your solution. part three: max wants to run a total of three laps around the track, choose two additional lanes (2-8) for him to run and find the distance around those two lanes. show your work and round to the hundredths. part 4: based on your lane choices in part three, what was the total distance max ran in the three laps around the track?
