Answer 1

Answer:

96/x=0.48

x=9600/48=200

total number of students is 200.

if balls Is boys.

Step-by-step explanation:

Answer 2

Given,

In class 9th of a particular School,

The probability of choosing a boy = 0.48

Total number of boys = 96

To find,

The total number of students in class 9th of the particular school.

Solution,

We can simply solve this mathematical problem using the following process:

Let us assume that the total number of students in class 9th of the particular school is x.

Mathematically,

The probability of occurrence of a favorable event = P (favorable event)

= (Total number of occurrence of the favorable event) / (Total number of occurrence of all possible events)

= (Total number of occurrence of the favorable event) / (Total number of trials)

As per the given question;

The favorable event is the occurrence of a boy.

So, the frequency of occurrence of the favourable event = total number of boys = 96

And, the total number of trials = total number of students in the class = x

Now, according to the question;

The probability of choosing a boy = 0.48

=> (Total number of occurrence of the favorable event) / (Total number of trials) = 48/100

=> (total number of boys)/(total number of students in the class) = 48/100

=> 96/x = 48/100

=> x = (96×100)/48 = 200

=> total number of students in class 9th of the particular school = 200

Hence, the total number of students in class 9th of the particular school is equal to 200.
