Correct Answer: 3/5

Solution:

Probability = Number of girls / Total students = 18/30 = 3/5.

In a class of 30 students, 18 are girls. If a student is selected at random, what is the probability that the student is a girl?

In a class of 30 students, 18 are girls. If a student is selected at random, what is the probability that the student is a girl?

Step 1: Identify the total number of students in the class. In this case, there are 30 students.
Step 2: Identify the number of girls in the class. Here, there are 18 girls.
Step 3: Write the formula for probability, which is: Probability = (Number of favorable outcomes) / (Total outcomes).
Step 4: Substitute the numbers into the formula. The number of favorable outcomes (girls) is 18, and the total outcomes (students) is 30.
Step 5: Calculate the probability: Probability = 18 / 30.
Step 6: Simplify the fraction 18/30. Both numbers can be divided by 6, which gives us 3/5.
Step 7: Conclude that the probability of selecting a girl is 3/5.

Probability – The likelihood of an event occurring, calculated as the ratio of favorable outcomes to the total number of possible outcomes.
