What is P (boy)?

Answer 1

Given:

• There are 15 boys and 13 girls in her class.

To find :

• Probability of the boy's = ?

Step-by-step explanation:

Question is saying that Mrs. Avery is randomly select one student from her class to read a poem out loud.

And, There are 15 boys and 13 girls in her class. [Given]

And it is Asking that What is the Probability of boy's.

Now,

Finding the Probability of the boy's,

Firstly we have to find the total number of students in whole class,

Total number of students in whole class = Total number of girls + Total number of boys.

Substituting the values, we get,

= 15 + 13

= 28.

Therefore, Total number of students in whole class = 28.

Now, Finding the Probability of the Boy's,

Probability of Boys = Total number of Boys /Total number of students.

Substituting the values, we get,

= 15/28

Hence, The Probability of Boys in fraction form = 15/28.

Now,

The Probability of Boys in decimal form,

= 15 / 28

= 1.87.

Therefore, The Probability of Boys in decimal form = 1.87.

Answer 2

Given:-

Total number of boys in the class = 15

Total number of girls in the class = 13

To find:-

The probability of selecting a boy

Solution:-

Probability of a boy for being selected by Mrs. Avery = P(boy) =

$\boxed{number\ of\ favorable\ outcomes\ /\ number\ of\ total\ outcomes}$

P(boy) = 15/(15+13)

          = 15/28

∴Hence, the P(boy) is 15/28.
