Question

#2

There are 25 students in a class.
Fifteen are boys and others are girls.
A student is selected for a field trip in
random.
Find the probability of
selecting a girl.

Answer 1

P(girl) = 40%, 2/5, or 2:5 (depends which one they're asking for)

Explanation:

First, you need to find the number of girls in the class. Using the information given, in order to find the number of girls, you need to subtract the number of boys from the total number of students in the class (25-15). By doing this, you will see that there are 10 girls in the class. Now, in order to find the probability of choosing a girl, write the probability as a fraction (# of desired outcomes aka any outcome in which you choose a girl - numerator / # of total outcomes aka total number of students in the class to choose from). This will give you the fraction 10/25 , which simplifies to 2/5.

Hope this helps!!! Good luck!!!
