a student is chosen at random from a 7th grade math class of 16 girls and 8 boys. find each probability

1 answer:

4 0

There is a total of 24 students in the class.

The probability of choosing a girl is 16/24. Which reduces down to 2/3 or 66%.

The probability of choosing a boy is 8/24. Which reduces to 1/3 or 33%.

So the student has a 66% chance of choosing a girl and 33% chance for a boy.

tangare [24]

GCF stands for greatest common factor so if u have a problem like let's say, "What is the gcf of 36 and 90?" all u do is go down your multiples table and write them all down till 36 you will get 9 and if u take 10×9 it equals 90. For LCM all you do is go down your multiples table and find the least number that is the same with each other.
