Answer:
Probability that a boy will answer the question =
Step-by-step explanation:
In a certain class of students,
Number of boys from Wilmette = 11
Number of boys from Winnetka = 5
Number of boys from Glencoe = 4
Total boys in the class = 11 + 5 + 4 = 20
Similarly, total number of girls in the class = 7 + 4 + 4 = 15
Total number of students in the class = 20 + 15 = 35
Now number of ways we can choose 1 boy out 20 boys
=
Similarly number of ways, we can choose a boy out of 35 students =
Now the probability that a boy will answer the question =
=

Your answer would be 3/7 or
____________________________________________________
Step-by-step explanation:
In this type of question, we would need to find out the chances of getting something as an outcome, and that would be expressed as a fraction.
In order to find out the chance (or likeliness) of an outcome, we would need o use the information provided in the question.
Let's give you some key information that was given to us.
Key information:
4 animal characters
3 Human characters
With the information above, we can figure out what would be the probability of an outcome.
The question is saying "what is the probability of the computer picking a human character." That means that the amount of human characters would go on our numerator.
There's not only human characters, but there are 4 animal characters too, so that would be used to give us our total. the "4" will be added to our denominator.
Now, let's write it in a fraction.
Fraction:
We know that we are trying to find the probability of getting a human character, so "3" would go on our numerator.
For our denominator, we would add up both numb ers since it would have to be the total amount of options in order to find the probability, and that would be "7" since 4 + 3 = 7.
When you put those into a fraction. Your FINAL answer would be:
3/7 or
