Sometimes Latex can be a real monster.

Let me just put into language what I think you mean.

Givens
Number of boys = 15
Number of girls = 13

Total number of students = (15 + 13) = 28

P(boy) = 15 / 28  or in decimal form
P(boy) = 0.5357

Answer:

[tex]0.54[/tex]

Step-by-step explanation:

Probability = Number of favorable outcomes/ Number of posssible outcomes

There are [tex]15[/tex] favorable outcomes (the [tex]15[/tex] boys).

There are [tex]28[/tex] possible outcomes (the [tex]15 + 13 = 28[/tex] total students in the class.)

P (boy) [tex]= \frac{15}{28}[/tex] ≈ [tex]0.54[/tex]
