There are 24 students in a class. One student will be randomly selected as representative on the student council. if there are 9 boys and 15 girls in class, what is the probability that the representative will be a boy?
9/24 = 3/8
To find the probability that the representative will be a boy, we need to determine the number of favorable outcomes (i.e., the number of boys) and the total number of possible outcomes.
In this case, there are 9 boys and 15 girls, making a total of 24 students. Therefore, the total number of possible outcomes is 24.
Since we want to find the probability of selecting a boy, the number of favorable outcomes is 9 (the number of boys).
Now, we can use the formula for probability:
Probability = Number of Favorable Outcomes / Total Number of Outcomes
Plugging in the values, the probability of selecting a boy as the representative is:
Probability = 9 / 24 = 0.375
Thus, the probability that the representative will be a boy is 0.375, or 37.5%.
