You can put this solution on YOUR website! When cn\hoosing a student among the all the students to choose from, the probability that any particular student is chosen is the same.
There is a probability that the first choice is a math major.
For the second choice there are math majors left among the students left to choose from, so the probability that the second choice is also a math major is .
The probability (to three decimal places) that both of them are math majors is
