Answer: 
Step-by-step explanation:
Given, A class has five boys and nine girls.
Total students = 5+9=14
Number of ways to choose 6 students out of 14=
[Using combinations]
Number of ways to choose 4 girls out of 6 (4 girls + 2 boys = 6 ) = 
If the teacher randomly picks six students, then the probability that he will pick exactly four girls:-


hence, the required probability =
.
I'm guessing these problems are meaning multiplication in which you need to multiply them but don't worry here is your answer.
6 * 36,200 = (217,200)
21 * 8,050 = (169,050)
Subtract your totals which gives you (48,150) is your answer!
Hope this helps.
Have a great day!!!
Answer:
1. To convert cubic inches to cubic feet we divide the figure by 1728 (there are 1728 cubic inches in a cubic foot).
2. Measure the length, width and height of the box in inches. 2. Multiply the length, width and height and divide the resulting number by 1,728. This is the container's volume in cubic feet.
Answer: There are 8 3/4 in 6
You can use a rule of three:
If in 3/4 there is 1 (3/4), How many 3/4 are in 6?:
3/4 → 1
6 → x
x=(6)(1)/(3/4)→
x=6/(3/4)→
x=(6/1)/(3/4)→
x=(6/1)(4/3)→
x=(6)(4)/[(1)(3)]→
x=24/3→
x=8
