Answer:

Probability of a selected student is a girl =

Step-by-step explanation:

Given

number of boys in a class = 60

number of girls in the class = 40

Total students in the class = 60+40

= 100

Number total possible outcomes (S) = 100

According to the problem given,

If a student is selected at random ,

Number of favourable outcomes (E) = 40

Now,

Probability of a selected student is a girl = E/S

= 40/100

= 2/5

Therefore,

Probability of a selected student is a girl =
