Using Probability formula,
The Probability that elected student is a girl is 2/5.
Probability is defined as chance of occuring an event . The value of probability of an event is lie between 0 to 1.
we have given that,
total number of students in class = 25 i.e total number of possible outcomes = 25
total number of boys out of 25 students = 15
One student is randomly selected out of 25 students.
We want to find the the probability that the selected student is a girl.
total number of girls in class = 25-15 = 10
total favouable outcomes (that's girl is selected)
= 10
Now, probability that the selected student is a girl is 10/25 = 2/5 .
Hence, probability that a girl is selected randomly from a class is 2/5 .
