A small class has 9 students, 6 of whom are girls and 3 of whom are boys. The teacher is going to choose two of the students at
random. What is the probability that the first student chosen will be a boy and the second will be a girl? Write your answer as a
fraction in simplest form.

Boy: 1/3 chance (33% chance)

Girl: 2/3 chance (66% chance)

Step-by-step explanation:

girls: 6

boys: 3

girls to boys ratio: 6:3 out of 9

boys probability: 3/9

simplify (divide 3/9 by 3)

1/3% chance

girls probability: 6/9

simplify (divide 6/9 by 3)

2/3% chance

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
