A middle school football player, Bo, is just learning how to kick field goals. Currently, he only makes 1/3 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, or 6 represent a missed field goal. Use the following 20 trials of rolling a fair number cube to answer each question.
2436 4251 6233 5316 5212
6643 5326 5313 2152 4164
3642 3554 6413 2563 4533
2512 6634 4536 2112 5546
a. The estimate of the probability that Bo makes three or four field goals is .
b. The estimate of the probability that Bo does not make any field goals is
