If a student is selected at random from a group of 20 students, 12 of whom are boys, what is the probability that the student is a boy?

If a student is selected at random from a group of 20 students, 12 of whom are boys, what is the probability that the student is a boy?

Step 1: Identify the total number of students in the group. In this case, there are 20 students.
Step 2: Identify the number of boys in the group. Here, there are 12 boys.
Step 3: Use the formula for probability, which is: Probability = (Number of boys) / (Total number of students).
Step 4: Substitute the numbers into the formula: Probability = 12 / 20.
Step 5: Simplify the fraction 12/20. Both numbers can be divided by 4, which gives us 3/5.
Step 6: The final answer is that the probability of selecting a boy is 3/5.

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