Answer 1

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 2

Answer:

$0.54$

Step-by-step explanation:

Probability = Number of favorable outcomes/ Number of posssible outcomes

There are $15$ favorable outcomes (the $15$ boys).

There are $28$ possible outcomes (the $15 + 13 = 28$ total students in the class.)

P (boy) $= \frac{15}{28}$ ≈ $0.54$
