Step-by-step explanation:
Ok, so at first, the probability of the teacher picking a girl is 7/9. And then when she takes one girl, it is less, so the probability is 6/8. Then if she picks 2 more girls, then the probability of that would be 4/6, or 2/3.

Answer:
0.75 lbs.
Step-by-step explanation:
Okay, this one is more simple. To find the weight of each book, You have to solve this division problem:
15/20

So, the answer is 0.75 pounds.
