Answer:
1/3
Step-by-step explanation:
No. Pg grils are 160 therefore boys will be 80
As 160 + 80 = 240
Therefore p(no. Of boys)
= No. Of boys / total no. Of boys
= 80 /240
= 1/3

Answer:
total no. of students = 240
no. of girls = 160
no. of boys = 80
P(E) = no. of favourable outcomes/total no of outcomes
P(student choosen is a boy) = no. of boys / total no. of students
= 80/240
= 1/3
