Question

mrs. avery is going to randomly select one student from her class to read a poem out loud. there are 15 boys and 13 girls in her class. what is p(boy)? if necessary, round your answer to 2 decimal places.

Explanation:

Step1: Calculate total number of students

Total students = Number of boys + Number of girls = \(15 + 13=28\)

Step2: Calculate probability of selecting a boy

Probability formula \(P(\text{event})=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). Here, number of favorable outcomes (selecting a boy) is \(15\), total number of outcomes is \(28\). So \(P(\text{boy})=\frac{15}{28}\)

Step3: Compute the decimal value

\(\frac{15}{28}=15\div28\approx0.54\)

Answer:

\(0.54\)
