A middle school football player, Bo, is just learning how to kick field goals. Currently, he only makes \frac{1}{3}31​ of his kicks. A number cube is being used to simulate the result of Bo’s kicks where the numbers 11 or 22 represent a made field goal and the numbers 3,4,5,3,4,5, or 66 represent a missed field goal. Use the following 2020 trials of rolling a fair number cube to answer each question. ​ 24362436 42514251 62336233 53165316 52125212
