Q: If a student is selected at random from a group of 10 boys and 15 girls, what is the probability that the student is a girl? (2023)

Solution: Total students = 10 + 15 = 25. Probability of girl = 15/25 = 3/5.

Steps: 6

Step 1: Count the number of boys in the group. There are 10 boys.
Step 2: Count the number of girls in the group. There are 15 girls.
Step 3: Add the number of boys and girls together to find the total number of students. 10 boys + 15 girls = 25 students.
Step 4: Identify how many of the total students are girls. There are 15 girls.
Step 5: To find the probability of selecting a girl, divide the number of girls by the total number of students. This is 15 girls / 25 total students.
Step 6: Simplify the fraction 15/25. Both numbers can be divided by 5, which gives us 3/5.
