Asmall class has
10
students,
6
of whom are girls and
4
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.

Step-by-step explanation:

The are no replacements.

For the selection of the first student, there are 10 students, 4 of which are boys. So there is a 4/10 = 2/5 probability that the first student chosen is a boy.

Now, for the second student. There are 9 students, of which 6 are girls. So there is a 6/9 = 2/3 probability that the second will be a girl when the first was a boy.

So

step-by-step explanation:

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
