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
The practical domain would be all integers 10 to 50.<span />
