Answer 1

According to the given table, the number of students that passed the test and did not complete the homework is

`3.`

Also, from the table, we get that the total number of students that passed the test is

`11+3=14.`

Therefore, the probability that a student that passed the test did not complete the homework is:

`(3)/(14)\text{.}`

Answer:

`(3)/(14)\text{.}`
