The score distribution shown in the table is for all students who took a yearly AP statistics exam. An AP statistics teacher had 48 students preparing to take the AP exam. Though they were obviously not a random sample, he considered his students to be "typical" of all the national students. What's the probability that his students will achieve an average score of at least 3?

Probability that his students will get at least 3 is 0.9875

Step-by-step explanation:

In the given scenario the number of favorable outcomes are 3 out of 5 that  is 3,4,5 out of five.

  Probability = no of favorable outcomes/ sample space  

Probability his students will get 3 or more = 3/5/48= 0.6/48= 0.0125

Probability of at least getting 3 or more = 1- Probability of getting 3 or more

Probability that his students will getting at least 3 = 1- P( 3 or more)

                                                                                  = 1- 0.0125

                                                                                     = 0.9875
