Respuesta :

Answer:

0.789 I think that is the answer

Answer:

Step-by-step explanation:

draw Venn diagram

passed test ---- both - did assignment

20-16=4 -------- 16 -------- 19-16 = 3

4 + 16 + 3 = 23 who did something useful

that leaves 28 - 23 = 5 outside your diagram who did nothing

16 out of the 19 who did the homework passed the test

so

16/19 = 0.842
