attashe74 [19]

Answer:

.571

Step-by-step explanation:

We need to find the total number of boys

11+5+4 = 20

And the total number of students

11+7+5+4+4+4 = 35

The Probability that the student is a boy is boy/total

P (boy) = boy/total

           = 20/35

           =4/7

            =.571428571

  to 3 decimal places

           =.571
